Manipulated the price of certain crypto, and monopolized e-commerce.

Speculative bubble getting bigger and bigger by attracting greater and greater fools. No matter what Elon does or says, it's just a zero-sum game. What would the humanity lose if Bitcoin disappeared right now? Absolutely nothing (except people who hold it would lose their "investments").

To the second point, you should look into the definition of monopoly. Amazon is a behemoth, not a monopoly. And they have created immense value.

Yes, that crypto thing was a real damage for humanity.

The people who are hurt by dips whether artificial or not are invariably going to be new, small time investors.

Even if you think they shouldn't gamble with their money I find it hard to argue there was no damage done.

What about gains from allegedly manipulating those cryptos up? Are those universally good for humanity?

God no, I'm no crypto-nut don't get me wrong.

Propping up a bubble destined to pop is bad too, so why get involved?

Think of the millions of starving kids in 3rds world countries who might've been lifted out of poverty, but for Musk's mercurial tweets about Bitcoin.
