Space Travel and Governments
I was thinking about space travel, commerce, and governments. So here's some ideas I thought I'd throw out and perhaps somebody might make something of them. They may be completely useless too. It's not for me to decide.
I see four main reasons for space travel:
Growth/colonization. This is the "First Stage" of interplanet/interstellar travel. Nothing else exists without it.
Commerce/communication. This obviously occurs because trading to your next door neighbor provides a certain degree of profit, but trading with another nation provides a much greater wealth. Trading on the planet and system scale would provide wealth and resources off the scale of our current existence. And of course, as social animals, we like to hear news and gossip from those we don't live with.
Travel/tourism. This has been and always will be the privilege of the wealthy. At the interplanetary and interstellar scale, the cost will be extremely high.
Security/Military. As commerce occurs and the wealthy people of a society travel, steps must be taken to secure the space lanes and ensure that distant planets behave well. At the point where human beings can travel to the stars, it is relatively simple to annihilate a planet or population centers from space, with attacks launched from far away. Obviously great care and expense is necessary.
From these four reasons, I imagine a space-faring society that looks like the following:
You would see colony ships. They aren't all going to new planets, but old ones, ferrying people about to where they can fit and be most useful to the society. These ships would be as cheap as possible, as they only need to travel to one destination with their human cargo roughly intact. Colonists are likely not paying much for the opportunity to travel to somewhere else. They may be skilled workers that are needed elsewhere, and on a company's private transport with the costs billed to that company.
You would see heavy freighters that probably would never land on a planet, only docking at hub stations or small moons where cargo is split up into smaller shipments to and from the planets. They would be bare-bones efficient, and concentrate on getting the biggest bang for the buck. They would all be privately owned by supermassive corporations, as those companies would be the only ones able to afford transport on such a scale, and their profits would easily cover the high costs of interstellar travel. It is quite likely that these companies would take over the role of government between planets. In essence, government would exist on a local scale (perhaps encompassing an entire planet or system), and corporations would run the rest of the galaxy. Competition would drive efficiency and ensure that they alone could afford space travel, governments being too restricted by their taxes on a democratic (not willing to pay taxes high enough) people and their inherent inefficiencies found in every government.
Travel and tourism would be restricted to local (planetary) levels, except for the wealthy executives that run the interstellar trade market, or otherwise profit from it. Even this would be highly restricted and unusual. For the most part, sending a data capsule or robot is cheaper and more efficient than sending a person. Virtual reality and near-orbit tourism would satisfy the vast majority of exotic vacation needs, and would be quite cheap. The cost of a hyper-transport is relatively astronomical. Those desiring true interstellar adventure can sign up for the hard life of colonization, where they pay for their transportation costs with labor.
Any military that exists in the planet level would serve primarily in the defensive role. The costs would be very high, and the stakes even higher. A handful of nukes, asteroids, or even antimatter bombs can be launched from light years away and lay waste to a planet. The idea that hyperspace engines could be attached to such weapons causes even greater worry. It would be worth it to spend a tremendous amount of money on planetary defenses, for obvious reasons, but governments would only be able to afford it with high taxes on interstellar trade. This means lots of money, but increases the expense of interstellar travel that much more. Alternatively, the supermassive interstellar trade corporations could take the role of planetary defenders. They have a vested interest in keeping their markets annihilation-free, and they have the deep pockets to pay for nuke-protection. It seems that the ideal government in such a society would be none at all. Let the corporations take care of the big problems.
I think that what I've described is realistic, and the likely turn of events in the distant future. How many private individuals on this planet today own seaworthy vessels? How many private individuals travel to other countries or continents? If you look at commercial shipping, it is clearly dominant. Sure, we have cruise ships for people on vacation, but not many people actually can afford them. There may be some nations that can afford travel (say, the United States), but these superpowers are rare in the world. And while governments today control the seas with ships and planes, look how slowly they journey into the final frontier. Commercial satellites and space initiatives are taking over. And plenty of people complain now that government is controlled by business interests as it is. Is it unreasonable to see them taking over someday, not by military might but by wealth and influence?
So anyway, I figure there's some ideas in there worth using. Perhaps somebody can think of a small project to use them with. Complex in an intellectual way, but relatively short in terms of time to develop or play through.
The tiny shuttle pilot who chooses his own course may not be so common in the future.
