"Form an MVNO or partner with a telco and converge the ISP wifi box with a cell base station. "
The other thing they could with smaller cells is share physical infrastructure with non-telco operators. There's a bit of that going on (eg mastheads on water towers or office buildings) but with smaller cell size you'd (presumably) have less need for quite such height, and you could then use taller lamp posts, electricity distribution poles and the like?
I'm sure the owners of those assets could invent a millions reasons as to why it couldn't work, but if the MNOs want to one day make mobile connectivity more than a lie in an advert, then they need to start thinking this way.
