Give me 50 mill and I'll do it. I'm not even kidding, I have multiple targets and a viable plan. And yes I'm aware of the list of things you listed and roughly what it takes to do all of them. Sure for a layman or an unfunded expert it might be daunting. But thats what these companies spend hundreds of billions at. Just listing out the complexity of the process says nothing about why they still don't succeed at it. I'm pretty sure boeing would have and continue to list all the problems in sending a rocket to space for cheap, while spacex continues doing that. Nothing different here.
