I'm not making a subtle or complicated point either. I think the start of it is that we had different ideas of what "worse" was being compared to.
You're saying "It's hard to tell a story where the wall is making things worse [compared to replacing it with nothing]." If the initially-unspoken bracketed condition is added, then yes, I agree with you.
My response was: "There might be a story where the wall is making things worse, compared to other things."
The issue is that your “compared to other things” essentially requires CloudFlare to be incompetent which, sure, that could be a thing. But then there are bigger problems.
None of your concerns hold up to scrutiny. Using lava lamps instead of better sources of entropy implies incompetence. CloudFlare is also not so resource limited that they can’t dump the lava lamp entropy in with the rest of their entropy sources. Or else, again, incompetence.
