Yah, I mean the video and question was sort of still in the realm of tree work, so I interpreted it as if I could do tree work without worrying about money.
Now if I had just stupid amounts of money, like tens or hundreds of billions of dollars, obviously I'd start a foundation to help solve the worlds problems, and do serious long-term investigations into corruption and injustice around the world. The kind of things that matter to the lives of millions or billions of people, but journalists simply don't have the resources or safety to dig into. Hell, I'd probably need a private army to protect myself if I did that, but with basically unlimited money, sure, I'll take a private army...
The post-scarcity Star Trek world sounds easier and more peaceful though.
