You could be right, but I think with a decentralized (peer to peer) exchange system, the parasites would have to go after each individual trader rather than collectivizing everyone regardless of what they are doing, just to make things easier for them. Then, if you are not operating in commerce, you won’t be lumped in with everyone who is and have to do all the extra work for them.
What we have in our favor is that they are wrong fundamentally. Imagine if when you buy a loaf of bread, the baker says, you have to work out how much it costs, and if you get it wrong I will prosecute you”
