Is centrifugal artificial gravity technologically possible for....?

Question

...a large space station in earth orbit at a height of 23,000 mi (geostationary) given 2021 technology? 
If so how large would such station have to be and how fast would it have to rotate in the space vacuum. I don't expect exact numbers or calculations (but are there any calculation formulas to figure such things out)?
Just discussion question because I never hear anymore such ideas (around since 1990's at least) discussed anymore.

Realists spoiled the show by calculating how much stress there would be on the structural member necessary to hold together a large metal tube weighing several tons per metre while it spun fast enough to simulate something like Earth gravity.

The beams would need to be so massive that the tonnage of steel required would be totally impractical to launch. Then don't forget the powerful rocket motors that would be needed to make the thing spin, and to stop it when it needed maintenmance.

Sure it is, if someone could come up with the Money

Here is the hint. On earth we feel gravity along with centrifugal force. To null out absence of gravity effect we need to rotate it in a way to centrifugal force generated will equal to resultant of earth gravity force and its centrifugal force.
