I have another simple catch, how the energy harvested by a Dyson Sphère is supposed to be transported to the planet where people live ? I suppose a direct cable is out of question, and I don't think wireless eletricity is possible, so what does remain ?
Batteries charged and after transported from the Dyson Sphere to the planet, and when empty, returned to the Dyson Sphere ?
Or maybe I'm missing something.

You are. You should read Bob Shaw's Orbitsville series for details of living in the Dyson Sphere.
Anyways. Dyson Sphere shell must be so thick and heavy material, that it already generates gravity in and out of the shell. If you want normal gravity, some unknown future technology will provide. There is also the issue of spaceships entering the Sphere, and it is also detailed in Bob Shaw's books.

Even assuming you could build one, the artificial gravity created by the rotation would only exist around the equator, diminishing to nothing at the poles. So only a natrow band would keep people and their stuff from floatin ofr into the bubble eventually falling into the sun.
How do Dyson sphere proponents solve this?

The shell is obviously very-very thick, to stand meteor hits. So it is already gravity generator.
To achieve earth normal, maybe only some hundred kilometers will suffice, because it is made of diamond-hard super-dense material.
