Earlier quoted context omitted.
Believe it or not, you can be financially successful and still be a bad person. Bernie Madoff wasn't the most moral person.
So you changed the argument to bad vs. not bad person. Don't you think there's a net benefit to Elon with Tesla getting literally all vehicle manufacturers to now seriously be on the path to mass producing EVs? How do you account or calculate that vs. whatever other behaviours he may engage in? Funny you bring up Ponzi schemes too, considering that's what Bitcoin is - just global and decentralized - with a few other…
If anything, the majority of post-bitcoin blockchains have in one way or another omitted key blockchain properties and therefore defeated the point of a blockchain, usually in the form of federated networks (private gate-kept chains), or, as you say, built with feature sets in order benefit ponzi scheme structures.
Lots of bitcoin hate lately, from environmental concerns (give me a break) now to "ponzi scheme". (Is it because there is a finite supply? Does that make buying gold a ponzi scheme too?)
Oh well, there's always been detractors.
