> Laundering millions is a huge amount of work already. You need to hide your criminal activity from banks investigating fraud. Presuming the banks are doing their jobs right, at least, but if they don't, then that'd be the place to start solving this problem.

It's not really clear that this is money that needs to be laundered, it's often irreversible transfers that are legit.

> People are already effectively faking addresses for something as stupid as Amazon reviews. Apparently it's that cheap to fake an address, because those crapware spam stores that rotate their name/products/listings aren't exactly the size of the mob.

I already responded to this below. Those don't involve scammer controlled addresses. If I send you a piece of physical mail with an OTP code, you can't use a random faked address.

> clearing the field for "professionals" while at the same time making identity fraud, address fraud, and (money) mules more lucrative.

The majority of this kind of fraud is already organized. That's why raising the cost is impactful, see my comments below. It's a tool to raise the cost of revenues to an ideally unsustainable amount.
