I think you might be missing the point of this comment: OP was saying that this is an additional expense involved in owning your own data. In reality, the people who would otherwise store your data aren't getting a lawyer for a warrant response, beyond validation that the warrant is legitimate. The "economy of scale" that 3rd party services have here is that they don't care if you go to prison.

Having a lawyer do the basics is really cheap. Having a lawyer fight the warrant or craft a minimally-revealing response is expensive. You don't have to break the bank if you end up getting served a warrant.
