I agree generally but this isn’t used for small sums. You’re talking hundreds of thousands / millions in highly visible ill gotten gains for it to be deployed.

Ok, but if you need to have hundreds of thousands / millions in highly visible ill gotten gains before you ask “wait, how he is making all this money without working” you have other problems

And I think 10k is a bullshit amount for this new law. People buy cars second hand all the time with cash fully legit.

Every amount you choose is bullshit. Even in Italy that the limit is 5000, paying under the table is not difficult, you just split the payments.
