Because it will be expensive, and IMO is way ahead of the consumer needs. And I'm talking about a country (Spain) that already has symmetric 1gbps commercially available, and the common connection is in the bracket of 100-600mbps. Replacing copper with fiber in remote areas is cheapish if you repurpose copper posts instead of digging, and the opex of fiber is even lower than copper. For those areas that are disconnected and don't even have DSL a few more BTs and 4G are waaay cheaper than putting 5G everywhere. And I'm not even mentioning the clusterfuck that is being changing all the bands and retool many stuff. 5G has really no upsides now, at least from my pov.
