This is close to what Britain has. The last mile infrastructure is owned by BT, who used to be a US-style monopoly, and now they have to give access to their infrastructure to the other ISPs. Unfortunately, quality is restricted by the fees BT charge being too high, and their general woeful underinvestment into much of their network. Having the last mile infrastructure be nationally owned would be a far better idea.
