That's the main problem - your legacy infrastructure is most likely wired for 220V@32amps for the whole garage/street just to run the lamps from it, so 7.2kW. That's one EV charger, or two if you want to split them into 3.6kW feeds. If you want to run a proper 7.2kW charger from every lamp post or next to every parking space, that's a lot of brand new cabling that you need to add.
The grid connection for one fast charger could serve 50+ L2 chargers, potentially even 100 with load-sharing chargers.
There are good use cases for both kinds.
A EVSE could easily serve multiple spots, and fairly (or unfairly, for profit!) distribute power between cars from a limited supply
With level 1 charging is only 3 to 7 miles per hour, so average of 35 miles in a 7 hour day (assuming you drive for your lunch break). Where I am, the average distance to work is around 27 miles (one way), so a net loss of charge.
Looking at the actual stats, you're a bit of an outlier: https://aaafoundation.org/wp-content/uploads/2023/09/202309_... (p. 12). The average commute trip is 22 miles, and keep in mind you also could use a level 1 charger at home.
For most, the purpose of living further from work is reduced total cost of living, especially if you're near a big city [2], where it's not usually an option. I save thousands a month by commuting a little, for the same number of bedrooms (which has a legal minimum where I am). If I wanted the same square footage, I'm saving > $10k/month, compared to being 1/3 the distance from work.
