Looking back, I think what he means is that "GPS" (even IFR certified units)
can not be used as sole means.

That is more-or-less true. If you're going to use the GPS to fly an approach
you're required to be able to get into an alternate without it.

Since the Garmin 430 contains not only TSO'd
GPS but also VOR, LOC, GS, etc., my position is that this unit (without any
other navigation equipment on board) is legal as a "stand alone" for use en
route, terminal, and approach

Yep. As a matter of fact, many new aircraft are delivered with only 430/530's
as nav equipement.

. (I know charts are still necessary.)

Charts are never strictly required for us small fry. As a practical matter, you
need them, but only perverse misinterpretations of the regulations require their
carriage.
