Sounds more like he's saying that companies should be held accountable, rather than continuing to allow any early access (including kickstarting!) project to simply walk away if they feel like it, leaving the customer no legal recourse.
I'm not the one to define those responsibilities, but I do agree with the general idea.
Early Access != hobby project, buying an EA game != making a donation.
And cars are sold before they're fully assembled all the time. Hell, before they even start being assembled. Pre-orders by the public and contract orders by dealers. There's a certain number they'll make, but that's in addition to all the ones that have already been sold. If the company fails to deliver the product as described, the customer is entitled to a refund.
Physical analogy not good enough for you?
Lets look at freelance graphic artists then. They get contracted to make assets for a product to a certain standard the company outlines. Artist fails to create these, or creates assets that fall outside the standard, they either wouldn't be paid, or would be liable in court.
Being that I've not seen a single case of an Early access game being sold without being licensed, they are all contracted works.
"as-is" is often thrown in there in an attempt to CTA, but that doesn't mean it's a valid stipulation. If a court decides a reasonable person would expect something, and that something is not provided/done/etc, then the court would find the company liable.
Furthermore, they could be held criminally liable under false advertisement among other things.
But the cost of going to court in the first place generally allows these kind of incidents to happen without legal consequence. So this is all just a fart in the wind.
