This way you could start over without having a bunch of pipe or what ever stuck in concrete you couldn't do anything with.
To prevent frost heave pour the footings down below the frost line.

I've thought about this, more-so when I was thinking about using 4x4 treated posts, (see earlier posts in this thread) as they would be easy to swap out when they rotted.
But several building forums mentioned that above-grade footers with anchors like you explained are for downward point loads, (houses, decks) and not so much for fences. The physics in my head seemed to justify their claim, but I'm by no means an expert.
