The examples like zippers and pianos are rather different from the social/political examples that are his real target. The difference is that the complexity of a piano is an inevitable feature of it (at least until someone invents a simpler version). But it is far from obvious that the complexity of the tax code, or the EU, or how schools are funded is functional. These political systems may be complex precisely in order to confuse the voters, in which case it is quite rational for the voters to try to push for simplicity - for example, avoiding the complexity of the EU by simply leaving it.
