By all means, go. But pay for it yourself. If you can't personally afford Mars, the middle of the Sahara Desert is unoccupied and overwhelmingly easier and cheaper to get established in. Or, under the ice in Greenland. Or, revitalize an abandoned whaling station on an island off Antarctica. If those seem uninviting, I promise Mars will be a thousand times moreso.

Your "golly I'm on Mars!" euphoria would thin out very, very fast. "This place f'n sucks!" malaise would grow steadily and without bound.

I'm definitely not going. But I'm very glad others will go!

Maybe that's a confusing distinction for some.

I would not mind if they went somewhere. If they went to Mars they would immediately stop talking about what a great idea it was, even if they still had air. They would shortly thereafter try to get somebody to bring them back home.

So we have this thing called a government that we give money too. Different people want it to do different things. You can recognize that while you may pay for things you dont want, other people are paying for the things that you want but they dont.
