By all means; spend your money however you want, but a few billionaires using their personal wealth to fund Mars colonization efforts "just because" isn't going to be nearly enough to build a self-sustaining city there. Musk is talking about sending hundreds of Megatons to orbit every year, for the foreseeable future[1]. He wants an armada of one thousand Starships departing for Mars every 26 months[2]. That's what it would take to build a self-sustaining city on Mars, and it's a multi-trillion dollar effort; not the sort of thing that can be funded by a few wealthy donors. The only way I can see large-scale Mars colonization happening is if there's a strong economic incentive for that. It isn't going to happen just because a few people want it to, or think it's the "next step for humanity".
