That would get you very cheap ISP with terrible speeds and a lot of downtime. There is no incentive for investment if they have to resell at (or near) cost. And we've seen this in action. DSL service was covered by Title II originally, which meant it had to be unbundled and resold. But cable internet had no requirement. Investment flooded to cable rather than telecom. Why would Verizon invest billions in a network that benefits third parties? Well they didn't. It was only after Title II repeal that Verizon went forward with Fios. Because it didn't have to resell. It's possible to do this sort of thing, but you have to build in a fat profit margin. But even then, the companies wouldn't have any incentive to provide good service.
