Why aren’t stock markets open 24/7?

Hey everyone,

I have a few questions about stock market hours:

1. Why aren't stock markets open 24/7?
2. What are the benefits and downsides of having limited trading hours?
3. How would 24/7 trading impact the market and investors?
4. Are there any specific reasons related to regulation or market stability that keep the hours limited?
5. Are you interested in 24/7 Market hours? Why?
6. What if stocks are on the blockchain? Would you want them?

Any stock brokers or experienced traders here who can enlighten the commoner?

Thanks!
