Doesn't make sense that increasing density from very low to merely low in an outlying suburb would result in cafes and bakeries. You're talking places already oriented to the automobile, where people drive to the whatever cafe or bakery they already like in a large area.

You're assuming that those local businesses can just spin up and wait what, months? years? for the density to reach levels that will sustain said local businesses. Most people don't have the money to throw down the drain like that merely wishing for the urbanist utopia to arrive. In the real world, money matters, timescales matter, customers matter, etc.
