Truly dedicated, sure. My IP on my home router hasn't changed in 3 years, one could build a residential proxy network build on similar. But the issues always come when the access to the residential changes hands - how this IP has a history that you may not want to be associated with.
This is why many people go to mobile. Though for some things, the IPs can get "banned" - not really for most, becuase the cell phone companies need Americans to be able to actually use the IPs to do normal things, and mobile IPs are, by definition, shared with everybody.
Many prefer "static" mobile which aren't actually static at all, but rotate normally usually every 24hrs while connected to a cell phone tower. These are quite popular for traditional "static" needs like client management of IG accounts. Very very popular, and much cheaper than rotating 4G proxies.
