And it's a public street. It's what inside the houses (URLs) that is not public.

Doors (holes-become-walls / walls-become-holes) are for controlling whether things can go through. URLs are for letting things through.

A url is not a door, but an archway, or possibly a door frame.

..and you're not allowed to walk into someone's house if they only have a door frame instead of a locked door. they are for preventing criminals from forcefully breaking in. but you don't have to break in to commit the crime. that's why it's called "breaking and entering" - there are two criminal acts committed.

An arch is not something that merely isn’t locked, but something that isn’t meant to even be closed.

Yeah you still can't just walk into the Mayor's office just because it's unlocked. Access isn't authorization.

And yet if I do just open the door to the Mayor's office and it's unlocked and I wander in, that's still not the same sort of trespass as entering someone's home.

And, if I'm in City Hall, the mechanism that keeps me from entering the Mayor's office should be the security guards and key-cards, not my disinclination to open a door.

And if you walk in there, realize it's a restricted area, and start opening up file cabinets and reading confidential documents, you're now in jail. the security guard being there or not makes zero legal difference - things not being locked or blocked does not give you rights to them. thank you for proving yourself wrong.

you mistakenly wandering in is not illegal. however your strawman is not what the OP did. it's a paragraph of text for crying out loud. please at least read the story before commenting.
