This is a thoughtful reply. I will just say that the UK also has public toilets all over the place, and a desire for people to not screw & get high in the cubicles. Ditto many other countries. But I've never been anywhere else with this door gap problem, where no-one gets privacy.
I did once use a UK bathroom in a supermarket where the lighting was all blue, which makes it hard to find a vein to inject. But the doors still closed properly.
What is easily understandable, in far less than 10 minutes, is that a) this is incredibly hard to follow, and b) your mass-posting this everywhere does not comes across well.
If, as you allude to, you have retained legal counsel, I urge you to ask them if posting this all over the place and getting into internet bunfights is likely to impact your case... and I also urge you to follow their advice when they advise you to stop.
