with mass services requiring mandatory phone number binding I think being in user mass is a viable option - you cannot get reliable “secondary” email anymore and people don’t look through data leak dumps by eyes anyway, script doesn’t care about email address string - it all becomes hash anyway. Whois protection is pretty reliable to divert snooping 3rd-parties.
As for expensive… yeah, sad state of affairs is that there’s nothing cheap about hosting your own infrastructure. Price of not really trusting anyone or having obscure technical requirements.
that’s cap, unlimited parts of autobahns are about the same in fatalities as speed limited highways. Although I doubt that it could be replicated outside of DACH countries, it’s more of a driving culture issue, people just have less ego on the road in Germany.
