Being permissionless and transparent is a great strength of Nostr. Not only do you know exactly what is public, but you can also use appropriate solutions according to your needs, like Tor or a VPN. Nothing is really stopping you, and that's very powerful.
I must say it's a pleasure to have people like @Seth For Privacy here. We need good awareness around privacy in every cyberspace, and Seth has done a great job in this area. We can definitely learn a lot.
