Regional jets and the smaller light jets such as the above companies
are introducing can use the shorter runways of GA airports, and
therefore become more efficient ways to travel. While it's early in
that curve, the idea is based on the already successful corporate
jet enterprises (that also use GA airports). So, it directly answers
your original question about the viability of GA.

A great deal of additional infrastructure would be required at many GA
airports in order to make them suitable for ordinary commercial
airline services, irrespective of the type of planes used. Just
flying planes that can accept a shorter runway would only cover the
tip of the iceberg.

How did you arrive at that conclusion? The GA airports that I fly out of
have "commercial airline services" of the type that I've described, above.
They are _charter services_, corporate and coop services, all of which are
flying under Part 135. It is precisely their difference from the
necessities of large carriers that make them viable, and part of that
viability is the far greater number of airports that can accommodate them.
