OK, so the US government has been recently shown conclusively to lie and spy on its own citizens, not to mention sending them to die on useless faraway wars, overtaxing them and maintaining a worrisome inequality regime for the benefit of only a few rich citizen. Clearly the US gov seems to be evil. Where are the righteous citizens taking up arms and bringing down that evil government?

Which well-armed milicia do you belong to?

I'm all for risky missions (any space flight is definitely risky, contrary to what people seem to believe on this board, has everyone forgotten about Challenger ?), but guaranteed suicide missions hold no interest. We want to go to Mars to establish something there, not to be there first and then die. That would be stupid.

Mars is a really tough goal by the way. We know of virtually nothing there that can be used for a return trip.

We've had the technical capacity to make durable metal items with numerical lathes for a long time, however it remains a skilled job. For the time being home 3D printing is more or less limited to making fragile plastic stuff. I can't see how that will soon start a revolution.

You will not find any fossil fuel on Mars or the Moon no matter how hard you look. Mars has very little atmosphere or indeed Sun energy input. It is difficult to think of a less hospitable world than the Moon. At this stage seeding either with people is not a sustainable solution and would not help Earth. So what use is it exactly?

No, resources on Earth and even the entire solar system including the Sun definitely are finite. We are not even talking about a very long time in the future. According to your theory at some point coal could become more expensive than diamond. But you cannot run a civilization on diamond.

Most economists would say that Western capitalism requires a growth rate of about 3% per year to keep everyone happy (low unemployment, funding, etc). At a sustained growth rate of 3% per year, we would be using the entire energy output of the Sun in 1000 years. Do the math. Civilization is a lot older than 1000 years. From this, two conclusions

1- Even the entire energy output of the Sun is a finite resource
2- Western capitalism will fail even in the not so distant future.

For those who would say "but we can make a lot of progress in 1000 years", I would like to point out that contrary to popular opinion, we haven't made that much progress since the 11th century.
