I have never in my life placed a sport bet, nor a polymarket bet. It strikes me as one of the dumbest things to do with your money and time.
But a lot of people seem to genuinely enjoy it. Gambling is part of human heritage. Regulate? Sure! Ban? I don't understand why
Many things that people enjoy are banned because it causes harm to other individuals or to society as a whole.
Not a difficult concept to understand.
Alcohol and tobacco are regulated too. Perhaps less than it should, in no small part for cultural reasons. I say this as someone that enjoys the occasional whiskey and smoking a pipe.
I am unaware of evidence of gaming causing harm to society. Maybe it exists. I can't comment on it.
