Especially as the majority of homes date back more than 25 years, and retrofitted cabling is very expensive.

And if you rent rather than own, you likely can’t add cabling at all under the terms of your lease.

A POTS phonejack can use pair(s) in CAT 5 (or 5e, 6), and newish buildings often already run it to the wall jacks rather than CAT 3. Depending on access to the other end of the lines, and appetite for DIY upgrading a landlord's building, it's quite possible to temporarily swap the RJ11 hardware for some RJ45 and have a wired LAN ;)

No building or home 25 years old has even Cat-3 in the walls. It’s all “uncategorized” cheap ass aluminum or maybe copper unshielded twisted pair.
