This is how New World does it too and it's fun as hell. Everybody wins. And you know what? Let's say you're curious about PvP just once. You can turn it on too. You might even win your fight.
Don't even need PvP worlds just the ability to flag it like WoW and New World. I kept mine on at times when exploring because who cares if you die. Today dying from PvP has no penalty - unlike the past. You die a lot in every video game you play. Get over it.
