I'm not going to argue that the asset forfeiture laws in the US are completely fair, but that's not how it works.

First off, you can't just arrest anyone without going in front of a judge and getting an arrest warrant (unless of course a police officer has evidence you committed a crime). Second, they need to identify your assets and then prove that they are proceeds from illegal activities. Do they just say "all of it is"? Probably and the onus is on you to prove otherwise.

Yes, it is more complicated than simply arresting someone and taking all of their stuff, but it's not right to say that they need to "prove that they are proceeds from illegal activities". Proving that you are involved with illegal activities is what a trial is for. If you haven't been tried yet, they haven't proven anything.
