You have some valuable points.

Naturally the internet is not a mesh network because nobody will take this role of gatekeeper without benefit. If somebody does, it becomes ISP again.

However, although the current web is messy, we should be able to organize it using distributed network solutions in a peer-to-peer manner, as proposed in the blog here: http://bit.ly/1e8vrLL. It serves an additional layer on top of the nature internet. It has the protocols built-in and the "Gatekeepers" sitting in between the distributed nodes and a feasible business model to support its execution, rather than the ideal Semantic Web solution requiring DRM.
