I think a reasonable analogy would be putting
TV's playing porn outside of a school and covered
them with a cloth and sign that said adults only.
Well, no. Anybody entering or leaving the school would have no choice but to see the covered TVs. Whereas porn is generally not showing up online unless you are looking for it.Strongly suggest dropping the analogies entirely.
Like many digital concepts this just will never map cleanly to a real-world analogue.
This is like the millions of bad analogies related to music downloads back in the Napster days. Please, stop. This is an issue worth discussing, but every analogy is bad and every analogy pollutes and enshittifies the discussion.
