I can see Elon Musk doing something like this.
Then NASA needs to let him do it on his dime, no government subsidies at all.
Almost all explorers have been financed by governments. Columbus, Magellan, Lewis and Clark, Chuck Yeager.
Individuals and small companies cannot afford to explore the unknown with the possibility of no payoff. That is why government pay for exploration.
We can’t learn to explore deep space without learning how to live in near space. Gotta have power.
