The main reason I think regulation is good is because it limits the use of funds for criminal purposes.
I see - this explains the reasons behind your stance on regulations.
We could, however, argue around the following points:
1. Aren't gains always made as a result of the Greater Fool Theory anyway (criminally or legally)?
2. Criminality is simply the opposite of legality.
3. Is legality about justice, or about power?
1 - I agree about the greater fool theory, however I fail to understand how that's related?
2 - Yes, it is.
3 - I agree with you that in some instances it is about power, but let's agree that it can also be about justice. For example, when opening an offshore company/ account: they don't care about taxes you may be evading, or anything like that, they just want to make sure you aren't using the account for one of the big 4 - weapons, humans, terrorism, money laundering for one of the above three.
