Of course, in such a new economy, if they invested, they would become investors. Also if they actually joined the organization with their own skills and their investment as cooperative members, they would also become investors, but worker-investors.

There is nothing wrong with that.

This is of course a far better situation than the current one, in which Musk has to appeal to and satisfy gigantic investors who already have billions of dollars. Who will not be satisfied with a return any less than tens or dozens of times their initial investment.

In a more egalitarian economy like I proposed, it would be much more easier to satisfy large amount of investors who don’t have billions of dollars. But more importantly, a great majority of people would already be satisfied financially — they would be investing in, or joining projects which they personally have an interest in. Which is a far better allocation of resource and people’s talents than the profit maximization system we have today.

Would Musk be able to fulfill that promise in such an environment…

But of course — not only the organization would be much more comfortable in pursuing its goals of reaching Mars, but also it would have the power of the masses to do that. Just like how Open Source movement and how it revolutionized software, then Internet, then our entire lives.
