I don't think there's anything noble about trying to avoid solving aids, loge - it's more to do with practice ('exercise' might be a better word).
If you have a word-matcher/anagram-solver regularly on tap, why struggle to learn the words? Why bother trying to piece together the typical patterns that occur in our language that help us construct anagrams?
I'd avoid word lists as well (getting a list of likely candidates and seeing which one fits will be far quicker than solving a clue - so why not dispense with the cryptic element altogether?).
Setters are only just ahead of us solvers - we'll have caught up in a few weeks when a novel word or synonym has done the rounds... as long as we take the trouble to register the novelty (and we've got a better chance of doing that if we've cracked the clue the hard way and checked out the wordplay/definition afterwards).
It would really help the process if setters could avoid those doubly obscure clues - using obscure wordplay to 'clue' an obscure entry seems altogether pointless (to me, at least). It gets interesting when a fairly common word is clued with doubly obscure synonyms, but that's about it.
I've got little to add regarding nobility/purity, or even what constitutes cheating - this is a crossword help site after all. I'm always happy to get a leg-up when I'm stuck and even happier when someone is prepared to point out to me something I've missed. I like the fact that solvers help each other to finish puzzles so they can enjoy 'the moment' (the PDM, or whatever) but I've got quite fixed ideas on how best to achieve that - for me it's really about 'Flow' (Csikszentmihalyi) and pleasure, not pain.
