Yes, that's what I mean. Attempting to tell people not to do something is like setting a robots.txt entry. Only a robot that agrees will play along. Therefore, all things have to be enforced server-side if they want enforcement.

Paywalls are a natural consequence of this and I don't think they suck, but that's a subjective opinion. Maybe one day we will have a pay-on-demand structure, like flattr reborn.
