The main problem I see here is that the law enforcement agency gets a (large) share of the money that gets confiscated. That makes it almost a commercial enterprise, and that's the part to change.
It's almost as if the people who are directing these agencies or parts of it are operating it as if it were a crime family or mafia, as far as profits - and murder (except in this case, "murder" means arrest or lifetime harassment from the LE) - are concerned.
Let's branch out of CM discussion for a moment:
How many cases can you count of crypto people getting harassed by LE? Definitely more than you have fingers or toes, that's for sure. There was this one US guy on this forum whose P2P trading service was considered an "unlicensed money transmitting service" and they raided him, and he made a website about that. Forgot his name. Point being...
Scales are tipped in the favor of those in power, so you have to try to avoid the lightning bolts that shoot out from them as a result.
