Hmm.. pretty much every telephone/power pole around is guyed by screw in 
anchors. Lots of other tall guyed things as well.  At least here in 
Southern California, for commercial installations they are VERY common 
(and there's a few companies who specialize in installing them. they 
have a truck with a hydraulic motor that drives them into the ground)

Maybe the key is that they are an "engineered" solution and require 
proper selection and installation. Screwing up either makes them a lot 
worse than expected.

There is an elegant simplicity and installation screwup proofness to 
pouring a bunch of concrete in a hole.
