Title II had special clause which requires owners of existing infrastructure to lease it to competitors (this was excluding by Wheeler when they reclassified it).
The leasing is what is necessary to enable competition.
We won't get competition if every ISP that wants to enter the market needs to run fiber to every house separately. It is very expensive, and if it wasn't, it is very impractical. Even Google with its "unlimited" capital wasn't able to enter the market. Think about that.
