Selling to someone else with higher price is always part of capitalism, and there's nothing wrong with that. Speculation is good for the economy.
Why I invest in tech stock? Because I believe the current tech companies might be 10x or 20x times the sizes in 20 years, and in 40 years they might be 1000x times the current size. Basically they could own governments and become world rulers. At least in metaverse.
Holy shit dude! I hope you are wrong on all accounts, especially the world rulers bit.
But more on point, what do you mean by size? Just valuation of their stock? Speculation on an asset makes sense when we don't know its inherent value. I can't figure out what is the inherent value of a stock any more. Does value not derive from utility now? Utility of a stock can be governance say (voting stocks) or a share in the profit. These companies with massive valuations don't generate any profits (see: Uber). So what are people speculating on actually?
