Why do we want to make the stock market mimic the crypto market? What need is the 24/7 trading solving? Just for hft companies to make more money? Seems like a genuine reason to diversify to Europe and Asian markets

As a practical matter as a "normal person" who just wants to rebalance/do a deposit/withdraw every so often, the market only being open 6:30 AM-1 PM on the west coast is very annoying.

6:30 AM to say 10 PM would solve a lot of those issues though without needing to go 24/7 (unless you work night shift...)

There's a reason the Black-Scholes model assumes market prices are continuous. The discontinuity of the market makes hedging options a lot more complex and expensive.

24/7 trading doesn't completely fix that, but it does help.
