There's a massive difference between your personally identifiable information visible to people who physically pass by versus people all over the world + various automated tools.
Also you're making a difference between license plates and doorbell names where there is no difference; it's only muddying the waters. The only difference is: visible to people physically close by is ok, visible on internet is not ok.
Germany... A place where you cannot publish a photo without permission from every person whose face is visible in it and yet people walk around with their faces uncovered all the time...
Less so than you may expect. Lots of apartments around here, including my previous place — if my name wasn't on the building doorbell, post just wouldn't get delivered.
(Sometimes post still wasn't delivered, as somehow even DHL couldn't find a 100 year old building and kept going to a different building on an adjacent street…)
Germany also requires an imprint with name and address on any non-personal website.
Non-Personal can basically mean anything beyond a purely personal blog without comments or anything.
