There are actually a lot of ways to beat torturer chains other than with your own chain.
Gardens deck, Watchtower, sometimes library, moat, lighthouse, strong trashing, basically any other curse-giver, embargo, often vault, sometimes horse traders, and, most importantly, just being faster. Heck, I'm not sure if Village+torturer is dominant on even half the boards it's on.
I certainly agree with the overall point that there are ways to beat torturer chains other than your own chain.
But, to pick nits: I don't really buy that library, watchtower, moat, trashing, or vaults are very effective counters 90% of the time.
If you buy enough reactions like moat or watchtower to have them in your hand consistently, you've probably screwed over your own deck pretty badly in the process, and village/torturer is nasty in that in addition to screwing your opponent over, it's a decent deck just as a cards/actions engine.
Library is fine if you have a ton of these expensive, terminal Actions,
and you can guarantee that you get hit by at most 2 Torturers per turn. I don't think that's a realistic scenario.
I don't really get how you think Vault counters Village/Torturer at all. Suck the 10 curses and discard them into Vault to turn them into effectively coppers? That's a hell of a soft counter.
But perhaps we're getting lost in the weeds. My ultimate point on Village/Torturer: the worst possible thing that you can do is say, "Oh, uh... I'll lose several turns in a row to having 0-1 cards in my hand." Either you should resign, or you should say, "I see a route to winning despite taking multiple Curses this turn," and accept the multiple Curses. You can't beat the deck by not taking any actions.
