Optional protocol-level privacy is no privacy, as we have learned, it can only be enforced. Otherwise, it risks becoming like Zcash - having amazing technology but only 12% of the network using it. Our observations show that most users won't set up or pay for a VPN, and since anonymous networks such as Tor and I2P are free, this may be a good reason for the full node software to switch to mandatory non-clearnet connections, moving away from clearnet and enforcing network-level privacy.
