Baloney. Once I'm in a position to fly visually to the airport/runway I
can do just that.

that's not what this says, I don't think:

(a) Instrument approaches to civil airports.

Unless otherwise authorized by the Administrator, when an instrument
letdown to a civil airport is necessary, each person operating an
aircraft, except a military aircraft of the United States, shall use a
standard instrument approach procedure prescribed for the airport in
part 97 of this chapter.

I don't see anything there that prohibits you from cancelling IFR when you
have sufficient visibility and cloud clearance to operate under VFR.

You can cancel when the reported ground visibility and your observed flight
visibility permit. Then, none of 91.175 has any application from that point on.
(you can't cancel in Class A airspace but that has no application to 91.175 in any
case.)

You can cancel any time you are operating in VFR conditions. Ground
visibility may or may not have something to do with that.

If it's reported and you're going to land at that airport served by the IAP, then it's
pertinent. Otherwise, it's not.
