On the contrary, you appear to be suffering the confusion that a service which facilitates a legally protected activity cannot be regulated, interfered with, or discontinued in the general case. Typically only targeted, motivated interference would constitute a violation.

Shutting down a notebook factory for dodging sales tax is not a violation of the rights of would-be purchasers.

I am fairly sure I am not confused. Instead I believe the post I am replying to didn't actually advance a coherent argument, but just appealed to emotions.

I am not sure that I have ever encountered anyone confused in the way you describe either...
