I have yet to see a TRSA encompass class G airspace (other than the
presumption that ground to 700 feet is included) but from a logical
standpoint it seems counterintuitive to provide "control" to traffic in
"uncontrolled" airspace.



The only place TRSAs reach the surface is within the core Class D surface
area. The outer boundary of a TRSA does not extend below the base altitude
of Class E airspace.

Please take a look at KRME on a sectional chart and compare what you see
to your statement above. The TRSA is charted as descending to the
surface in the immediate vicinity of KRME, which is Class G airspace
below 700'. A nearby airport has Class D airspace, however RME is not
in (or under) the class D airspace.
