Link doesn't fit but the argument stands. No billionaire-funded misison to Mars has ever succeeded. Not even SpaceX. You need at minimum an entire space program. Here's a better link: https://en.wikipedia.org/wiki/Mars_One
You didn't make an argument. You still haven't. Every new thing goes through a long stage where it hasn't happened yet. You haven't even begun to argue, with evidence, that this thing can't happen.
Even your line about "an entire space program" is incoherent in this context because the rocket in question is literally being used as a component in "an entire space program".
I fully disagree. Is that good enough to discuss? Name a private company that has landed on private devices on another planet. Here's the picture of where the argument stands:
Venus
Rocket Lab / MIT: Venus Life Finder: Late (Missed original 2023/2025 windows; now targeted for late 2026/2028)
Mars One: Conceptual Failure
Inspiration Mars Foundation: Cancelled
SpaceX: very, very, very late (timeline pushed to 2028+)
There's still nothing here worth debunking. But as long as we're trying to extrapolate from history and vibes, I'll just point out that your timeline is at least as plausibly interpretable as the early stages of a progression that eventually leads to a privately built rocket going to mars.
