Certainly, there are other market forces at play. Certainly carriers refusing changes and refusing to let a 3rd party authority sign their certs.

They haven't been solved on the web. Mobile phones have to authenticate themselves with the carrier to ensure someone is paying for their connectivity. Therefore they can't be anonymous. On the other hand, indeed, most of the time you don't have to identify yourself to connect to a web server — but once you have connected, you may face a paywall that requires authentication! Also, you are certainly authenticating yourself somehow with your ISP for your home internet connection.

Have they? The solution to IP addresses is basically "use a VPN", which you could do also on a phone. SNI leaks have been around since forever, and despite eSNI, still isn't close to being widely fixed. There's MAC address randomization, but only because LANs and wifi networks are basically an unregulated free for all, so spoofing doesn't really matter. It's far less viable with controlled access networks like cellular. Some countries even have regulations banning spoofing/changing IMEIs.
