What 'weight'? A good framework doesn't stand in your way, it lets u focus on business logic solutions instead of repeatable tasks.

Sooner or later he'll discover that he's getting to the point where he needs to provide solutions for problems that are already solved by a variety of well-maintained toolsets, and the lack of abstraction will make his projects hard to develop further.

I don't think he's really missing the point. This guy complains that he's always re-implementing the stuff that frameworks don't provide... but all of the stuff he talks about is just the basic features that every framework provides. He'd still have to develop those features on top of his homegrown framework.
