The first one is dispensed quite easily: if a person becomes a billionaire by lying about what will happen in the future, then the "wealth" is fake and obviously not earned.
That second one is very straightforward and can be addressed. You have to ignore a lot of obvious evidence to believe that coinbase, opensea, flock safety, one of the many gig startups... (to use a few of PGs billionaires) are a net positive force on society.
Thanks for educating me on the meaning of a valuation, but it's not really needed. Those "future cash flows" are eventually realized, and the first category converts into the second (in most cases).
You have to understand that when people are upset, they are upset about real changes that they see in their lives. They see the world that bezos, musk, peter thiel, etc are building, and they hate it. And yes, this group of people includes PG.
