As a business you have to issue invoices and you also have a responsibility to stop obviously criminal behavior.

A car dealership can’t sell somebody a Lamborghini if they want to pay with crumpled $20 notes. An art dealer can’t buy a Mondrian that the seller claims they found in their granny’s attic.

I don’t understand how this is controversial.

Neither of your examples seem obvious or objectively criminal, or uncontroversial for that matter. If you pull back from Lambo to a Civic, is this still obviously criminal?

classifying suspicious transactions is a weird and dangerous path to legislate.

Except that we're already there.

Domestically, cash above $10k is already subject to a reporting requirement, a new Honda Civic is $22k, and that much cash has been deemed suspicious due to the war on drugs.
