I'd agree on some of the other items though, OSS projects are important, as well as crowdfunding startups.
Hoarding/Saving helps the owner more than any one else. Let's not sugar coat the obvious.
Your argument of spending sounds essentially like trickle down economics. The benefit is that BTC is more used, a good thing. But if BTC is successful, we won't have to worry about that. Then it becomes another currency, but a deflationary one (and that can be problematic as we are seeing. Not a bad thing, but less likely to be spent.) People can do better than just spending some of their millions on cars, houses, food to help others out. Not that those things are bad in of themselves, they are just "selfish".
Of course we will use BTC but those many new millionaires, billionaires, etc. out there can do more to help to make a difference. That is what this thread is about.
Governments can't be fixed, to a large degree I agree. Disruptive technology makes them adapt to us though, just as with banking (I hope). And, even though governments are broken, they are essentially us.
Pa - Nice idea!
