They also claim that the TAA area minimum altitudes replace MSAs for

Although the TAA minimum altitude, and MSA have different definitions, I
never had a problem with the concept of them being the same value when
there is a TAA published.

Well, I don't see how they can be the same value when the MSAs don't
exist. MSAs provide 1,000 feet of obstacle clearance everywhere. TAAs
provide 2,000 feet in DMAs.

But, the greater concern is someone tortures the comparision to conclude
that MSAs, where charted, must now be IFR altitudes.
