To me the whole story certainly brought up a few things worth regulating. Why can brokers just arbitrarily decide to stop trading specific stocks? Why can different entities lend stocks for the purpose of shorting against the interests of the very owner of said stocks? Isn't shorting more than (or next to) 100% of the free float of a company too big of a risk for the whole system and how can we circumvent that in the future?
Before the whole thing, I had the impression, that stocks are safe. Not necessarily their price, but the stocks themself. I was aware that they are a separate asset and don't belong to the assets of the broker. Little did I know that brokers could still just lend them out and that I would only get a maximum of 20,000 € back over here in Germany, in case shit actually would hit the fan. I want to be able to print out my stocks and physically put them somewhere or put them on a blockchain! How is it possible, that in 2021 I could actually lose my ownership rights to a company, because someone else is using it to gamble?
