I had a big issue with glaring contradictions in your position until I re-read your series of posts. I've come to recognize you're conflating multiple related 'responsibility' concepts, swapping into the different modes when it's convenient. It's very similar to how you treated the term 'fair' earlier on. This is a common argument pattern for people who like winning pitched arguments against inexperienced individuals.

Your statements regarding legal responsibility, which is what you were critiquing (remember we're talking about contracts!), are all VERY wrong. But a lay person strolling through the thread wouldn't know it, so maybe your argument seems plausible. Half the time, though, you're not making a 'legal responsibility' argument but rather a 'moral responsibility' argument. The is/ought dichotomy exists, and is a common place where people get tripped up when discussing law.

The rest of the discussion isn't really worth having given that core miscommunication. That said...

>You arguing against straw man libertarian, not me.

You literally doubled down on the same position for three paragraphs in the very same post. lol
