This happens in sports betting as well, which is also regulated.
Neither of your examples show a material change or resolution due to regulation. The only result would be increased bureaucracy and decreased technology advancement.
I'm not sure how "still occur" became "the same result in both cases" - the latter is an extraordinary claim lacking any evidence.
Are you assuming that regulation is only admissible when it prevents every single event that is contrary to it?
Moreover, we are often seeing cases of regulation theater - the regulations in the books have convenient loopholes or are only selectively enforced, if at all.
Even in these cases it's a serious stretch to claim that the situations with and without regulation are materially the same.
Do athletes, refs, coaches still throw games? YES.
Your argument is that regulation would fix both, and my argument is that regulation has not fixed either. Wall Street is just as shady not with regulation as it was in the 1930’s without. The only major difference now is that the IRS is able to track and tax smaller entities easier.
