I believe because most 'Investors' in the space that have just arrived from Wall Street or Sherwood Forest are buying and selling nominal Ethereum on the Exchanges without ever performing an onchain action. Ethereum is utterly broken and 2.0 may never come.
Do you think this is a fair appraisal?
Investors from Wall Street or Sherwood Forest like you said are not the only participants on crypto market. Unfortunately, I don't have such a statistics on how many investors don't interact with Ethereum but invest only via exchanges, but still there are a lot of crypto enthusiasts that suffer from high gas fees, so I am sure that Ethereum's team will solve this problem one day, otherwise they will lose all users.
