For example why would Wallgreens install L2 chargers? People don’t typically shop at wallgreens for 4 hours and parking is usually at a premium so why would you encourage people to use your parking spots longer?

This is the opposite example. If you can think of the least useful places to install a quick charger you probably would have a hotel somewhere in that list. I would imagine that most people would stay at a hotel for at least 8-12 hours which would call more for a $200 L1 (120v) socket than a $25000 fast charger.
