So, can someone explain to me how massive corporations, investment firms, and governments buying up bitcoin by the thousands is a good thing?

Maybe I'm too monero-brained or something, but I can't see this as a good sign?

Bitcoin was designed to be a trustless peer-to-peer currency open to anyone. Not an investment vehicle or product for multi-billion-dollar companies.

I see people on here go nuts over the most recent news of Tesla or Microstrategy or any other nasdaq 100 tech firm buying up another few million dollars worth of bitcoin, but I don't see how that's good news. These companies aren't using bitcoin for their day-to-day operations, or accepting it for payment, or doing literally anything to practically support the network. They're holding it as an investment to sell off when people pump up the price based on hype. Don't even get me started on the ETFs.
