This must be a modern thinking that I have developed from bitcoin ecosystem and Satoshi Nakamotto: when you hate inflation, create your own money. This way, I cannot afford buying a tesla car but I own tesla shares. Yes, I also agree with OP.
You are right, why act like a stubborn kid, and buy something that comes with a lot of liabilities, while we can still buy their shares and can make money, once we make enough money we will also do the same as rich are doing, buy new tesla. This is a cycle that I think repeats from time to time, generation to generation. BTC and Satoshi's developments have made us realize the potential of investing.
TBH if it's not BTC, then I don't think I would be thinking of investing my money, even if I would be doing a job, either I will save my savings in fiat in some banks or I will buy some things with liabilities. But due to BTC I get into investing, and now I realize the potential of investing and trading as well.
