"Meh I'm okay with it" is by definition not a counterargument but rather a nonconstructive dismissal of whatever it is a response to.

You can in fact have both. You can have a tool that is fully functional and separately you can have a strategy for reporting suspected violations and responding to those reports. Reports can be automated assuming you can tolerate the false positive/negative rate. Particularly in the case of a subscription service such as Claude there is little reason not to implement this other than sheer greed or laziness.

In the case of Claude in particular, an unacceptably high false positive or negative rate also poses a serious problem for the current way they do things. The notable difference is that in the case of false positives it currently runs up a bill for the customer rather than the service provider.
