You only get to choose once
Picking a shop is not like picking a supplier. If the supplier disappoints you, you switch next month. If the building disappoints you, you are stuck with it for twenty years.
Location is a decision you buy once and pay for every single day afterwards, in freight, in wages, in how far customers have to come.
That is why the class calls it strategic, and why a whole family of methods exists just to choose a spot on a map.
