This is not a good post. This guy is addressing the cliff-notes one-sentence summary of the theory of induced demand, not the full thing, and hence this post is a pretty bad case of attacking a strawman. The more complete version goes like this: building more and bigger roads is a hidden subsidy to sprawl, since it allows people to live further away and in lower-density areas without having to pay the true costs of those areas. For details, see the many, many Strong Towns articles about how many suburbs and exurbs are functionally bankrupt because they never took their true costs of maintenance into consideration. The "induced demand" being criticized is fake demand, because this hidden subsidy is lowering the true price, and as any economist will tell you, demand goes up when the price goes down.
