It's my understanding that Tor is primarily a way to access the clearnet while darkweb access was added as an afterthought. I don't see Tor solving the problem of I.D. verification on social media, for example.

I2p was designed as a completely separate network. Haven't used it myself but this seems the way to go for most day to day activity.

Unable to watch porn.

Torrent the porn. I've seen plenty on offer at TPB.

Required to give your real name and ID in order to use social media.

Arrested for “mean tweets”, “anti-government views”, “liking subversive memes”, etc

Have your own domain from https://njal.la/ bought with Monero and create a single user instance for Lemmy or Mastodon should allow you to remain anonymous and avoid being arrested.

Only be allowed to use approved applications from Apple, Google, Microsoft, etc

Will Tor and I2P be approved by Apple, Google, Microsoft, etc? There will always be FOSS and there will always be a way to install alternative OSs on computers.

Set your downlink speed to 10-15mbps to acclimatize yourself

I've heard I2P is fairly quick, torrenting is encouraged.

Use bookmarks or password manager notes to have the URLs of your commonly used programs, services, and repos (#Monero, #XMRBazaar, #Pitch, #Dread, etc.)

Been doing so for years. You might have a hard time finding someone in the privacy community that doesn't do this.

Get used to text messages instead of audio or video calls. (Audio and video use UDP and generally give your real IP to either a central STUN server or the other peer. (it may be possible to force audio and video calls over TCP exclusively, but the latency would be high and therefore make the call unenjoyable.)

Messaging via Signal is my go to. Rarely do I even have my voip app active.
