Most of regulations on certain fields come from the fact that it's users are operating on a finite number of resources and areas, which do not expand proportionally to the userbase growth. Second of all, there often aren't efficient ways to avoid unwanted interactions, such as tools letting users selectively exclude the content of those environments. That's why people are more likely to accept regulations on those fields.

Internet is different in both of those aspects, and that's one of the reasons why applying regulations is artificial and recieves negative reception by the general public.
