Reading the NANOG thread about "The alleged evils of NAT", I wanted to come up with a semantic parallel, for the fun of it. Here it is:
NAT is like "tax optimization".
It's not illegal. But it may feel wrong.
It allows to represent things differently than you would think they are.
If you go too far with it, you end up in a real mess.
It brings very tangible benefits for those practicing it.
And those who don't - have to pay up on the communal goods for those who do.
Henceforth, they always argue with each other when they meet.
It creates a new profession dedicated to it.
As for my personal opinion, I'll just quote an anecdote: "it said 'celebrate', not 'celibate'".
