How about we don't? We really don't need to tie even more things to SIM cards and phone numbers.

Criminals have more than enough ways to still get anonymous SIM cards (at least until every country on the planet makes KYC mandatory for prepaid SIMs), and legitimate users are greatly inconvenienced by this.

To subsidize a network connection they probably already need for their business operations, e.g. their payment terminal or POS? Why should I? The marginal cost of an incremental byte on wired Internet connections is basically zero, these days. It's literally too cheap to meter, so why bother?

Besides the centralization and tracking concerns, not nearly every device has a SIM card. Why does my Laptop not deserve to access a coffee shop Wi-Fi, my Kindle to use an in-flight conenction, or my smartwatch to use the gym's network for podcasts?

It's very strange to me that people keep trying to willingly ruin the open Internet.
