Actually, Chomsky didn't appear in that clip. The point isn't even entirely about efficiency (although I would argue that deprivation and hogging of resources is not a true application efficiency, let alone firect democratic ideas). I haven't been totally indifferent to solutions. The solution is simple: Get rid of the authority titles and organize in an egalitarian manner.
Again, your points assume that the incentive for plumbing would instantly disappear if money did. You've just redefined human beings as incapable of performing tasks and retaining basic knowledge without money. But people needn't be perpetual children, nor are they. You fail to consider how people are literally compelled to be motivated by money, for they are not supposed to survive unless they have it. Obviously, that's a motivator. Exploitation and the domination is guaranteed to breed reliance when the only other option seems to be being a total outcast from social and economic life.
And any society set up in this way is obviously going to cause
problems.
As an alternative, consider Anarchists in the 1936 Spanish Civil War, which had in its name egalitarianism:

It wasn't perfect, but whatever is? Also, not all the Spanish anarchists totally eliminated the money idea, but that's not the main point. They wanted to basiacally do things for their own sake.
Just as pertinent is the practicality of not demanding that "someone else do chores for me."
Well, these questions have obvious answers. Yes, proximity is very important, and an individual with plumbing experience could certainly want to focus more on plumbing emergencies--especially ones closer to him/her.
If you don't want plumbing, that's your prerogative.
If anything, though, most people would go in the other direction. They would want to know more about mechanical skills, especially in an independent fashion.
I wouldn't say there is no use for some level of required status or qualification in certain types of work (for example, a doctor or an airplane pilot), but, even then it still comes down to knowledge and skills, without which
Not all is working correctly with capitalism, as you suggest. For example, there truly are auto mechanics who fix some parts to vehicles and sabotage others, or hospitals which don't treat patients with care. And there are companies who will fix water systems, only to come back and deprive them of water if the bill isn't paid in full (I've seen it happen). I would hardly call depriving people of resources the best, most rational and fairest way to organize society. In fact, it's indefensible. You haven't provided an argument for it, you just assume that because people can survive by following economic rules that these rules must be benign. They are not. They are grounded in inequality, in elitism, in distrust--and it follows quite naturally that we'd see all kinds of problems come out of this. People can still survive through basic solidarity under these conditions. But people have lived under all kinds of conditions and worked and survived. It doesn't mean an authoritarian archetype is the best people can do.
Seeing as to how you dismissed Chomsky's views, here is a much better, much more in-depth take on what anarchism could be like:
