although i agree with you, the argument breaks down because (at least in the us) most people don't know how to cook, and most people don't know how to drive or know anything - literally nothing - about how a car actually works. there are entire states where it's even illegal to pump your own gas.

have you looked at what people buy, even at high end markets like whole foods? it's an endless sea of prepared and packaged food. it's how they make most of their profits. whole foods isn't even expensive for real ingredients.

competent well rounded people like that are in the tiny minority. i would guess 10% or less. the cross section of people who are capable of both like you or i and others on hn has got to be minuscule. in fact i would bet the anti-car pro-Soylent contingent is bigger.
