Does anyone know why the FAA doesn't just put class D airspace around
these airports?


Probably because it would have an adverse effect on operations.
Aeroplanner.com shows 34 helicopters based at GPM. Put a Class D surface
area there and there'd be a lot of requests for SVFR whenever the weather
was below VFR minima. SVFR aircraft have to be separated from each other
and from IFR aircraft.



This would make for a nice blue dash line on the map to
show the point the local tower must be contacted.


You're free to draw a nice blue dash circle around these airports on your
sectional.
