If someone hasn't said specifically whether they like uninvited visitors then I don't see what the problem is of visiting them, if it's a problem with them i'd leave.
When I open my gates I put it on my 3ds friend message so people know they can visit me..
Obviously I'd respect peoples towns when I visit without having to be told - it's a no brainer, I wouldn't like someone stealing my flowers so why would I do the same? But ultimately I wouldn't want to swap codes with those rules that i've mentioned.
You are saying 'if someone hasn't said specifically' but are complaining about folks town rules, if there is a town rule saying they don't like random visitors then they HAVE stated that you shouldn't appear randomly.
Tbh, even if someone doesn't have it stated it is still rude to show up unannounced. Asking to visit doesn't take much effort.
If it is too much effort to ask to go to someones town then just don't visit someone who doesn't like random visits and delete them from your friends list and move on with your life.
