In theory you can have more potential customers inside the same radius, but there's also external factors to keep in mind, like rent. A small family-owned piano studio can make it in an ordinary, dowdy strip mall. The densest part of Boston has high rents that require you to have high traffic, so things like chain coffeeshops and high-volume drugstores are going to dominate.
This is the same reason why "Strong Towns" is fundamentally flawed...one faulty assumption is that all roads cost the same in maintenance costs. You can average maintenance costs and come up with a number, but you can't re-apply that back everything. Road maintenance depends on a lot of factors, one of which being the type of traffic it gets. An urban street is probably going to get 10 times the amount of total traffic a residential street gets, especially if there are commercial businesses which almost always require bigger trucks to come by regularly.
