"Just cut off internet" indeed would work... but it would work for a lot of things. But saying that is same saying that a normal bank is useless because the government can just "just cut off the power" and thus the bank servers would be down.

Another use is create business that can't operate in some jurisdictions for whatever reason (for example because sanctions, or just plain old outdated laws that were forgotten).
