Having gold-equivalent reserves seems like the very last thing that Martian colonists need to worry about. I would suspect "how do we survive in an extraordinarily hostile environment with no hope of rescue when something goes wrong" is a higher priority one to solve.

How will the colonists pay for their oxygen? This colony will not be cheap, they'll be expected to earn.

This level of thinking is exactly why we're so far away manned exploration of the solar system. Early colonists absolutely cannot treat these missions as business expenses.

Every colony is expected to earn, this is the history of colonialization.

For Mars colonization, I was also speaking to the nature of its backers.

The problem with a Martian (or even lunar) colony is that... there's not actually anything valuable there. So a traditional "earning" colony is basically off the table, and aside from the technological hurdles, is probably why the drive to do it just hasn't been there. Of our closes celestial neighbors, well, Venus is just useless entirely what with how hostile the atmosphere is to our... everything, Mars is quite far away, several months via current technology, and it's incredibly, devastatingly thin atmosphere and lower gravity means any given colony will require a lot and I do mean a LOT of support from us here on Earth to function. Colony isn't even really an appropriate word here, as colonization implies some level of living at the destination and between the lack of breathable atmosphere, lack of any and all flora, and lack of water, you're basically requiring regular supply drops or everyone is just dead.

Really the moon is far better in the transit aspect, which since you're supplying your colony from here, is a huge data point. And even then, what does that colony then do? The moon doesn't have much of anything we're really hurting for, certainly nothing to make up for the exorbitant cost of mining there. I could see it as a valuable location for low-G construction of larger, further-going spacecraft I suppose? But in terms of "expected to earn," I think either the red planet or our friend in the sky is going to be pretty dire.

When your colpny's line of support is a bubble om your head and a single sensitive means of transport, you don't want people thinking in terms of monetization. We can save taxation for the 24th century if and when we manage to terraform mars and make planatery transport not cost trillions of dollars.

But yes, I agree with you on the backers. That's precisely why I don't think they will be the ones landing Mars.

How will they pay for gold or bitcoin??

[ToucanLoucan]

See, I want to agree with you, but at the same time we are actively burning our only habitable planet because the rich refuse to give up any money. So I guess, if we only send poor people to live on Mars, this will probably hold? But if there's one rich guy up there he'll probably kill every last person with him if you don't make sure he gets paid.
