There are, though, rules about what you can point at the sky, and where.

There is no freaking way we can build a self-sustaining mars colony that could survive the destruction of humanity back on earth. Not now, and not anytime in the next century or so.

Right now, absolutely not. A century from now… I’m a whole lot less sure, a lot can happen in a hundred years. But let’s say it does take a hundred years. So what? There’s a whole lot of young people alive today who will still be alive then. Heck, I might be, depending on the rate of progress in medicine. Am I not supposed to care about that?
Besides, is it not sometimes worthwhile to put a down payment on a project that will take over a hundred years? I mean, there are cathedrals that people spent well over a century building. Is mankind no longer capable of thinking like that?
