who's to say OP hasn't suffered or otherwise disadvantaged himself in upholding that moral?

Exactly. Plus, many people don't seem to understand the word "avoid" (it's come up in my own bubble recently). It doesn't mean "never." For example, a vegan would not say "I avoid eating meat." Furthermore, because someone successfully avoids now doesn't mean they went through a period of being unable to in order to earn the privilege to do so regularly.
