IP Bans are usually pointless. Not all ISPs give a connection a static IP or even solely an IP (DSlite). The reason is they don’t want private people hosting stuff and generating more traffic and they can charge you more.
My ISP (Vodafone Cable in Germany) didn’t even gave me an IPv4 to use (it’s called DSlite/Dual stack lite), meaning I was behind a NAT on their end and many shared that IP. I did ask them nicely if I could get a real IPv4 for certain stuff and they gave it to me, but only when I book the upload boost for 5€ + a month. It’s not static but it only changes when my router is disconnected for a long time (I don’t know the exact time but at least several hours up to an day).
So usually an IP ban makes only sense for a limited time or specific ranges from companies (for example VPNs or hosting services that don’t care who books their service).
Shared IPv4 addresses are not to deter hosting but because there aren’t enough v4 addresses to go around. Most ISPs will happily give you an entire block of persistent IPv6 addresses but won’t give you a v4 because of address space exhaustion.
I kinda worded it wrong. Some ISPs do give out full IPv4 addresses but do rotate them, because they can and do charge more for static IPs. This doesn’t have something to do with a lack of v4 addresses. Only DSlite has something to do with the lack of v4 addresses.
