So what's the plan for the masses who don't have garages?
Thats a good question, actually, but all we can do is speculate because we dont know what Tesla plans. With that being said...
My speculation is, Tesla likely considers the demographic of "No garage / Parking space next to the residence available to charge at home, but still want to charge at home" to be a very niche demographic.
In many cases, either a person can charge "at home" either in their garage, or somewhere fairly close, where they can have electrical run to", OR, will be in a situation where they will be supercharging / using other chargers.
The number of people who fall into "I can charge at home, but I need a 40-50 foot cable to do so" is probably small enough that tesla feels that need can be met by that person engaging in whatever they need to do for their specific circumstance (Installing a wall connector close to their parking, or getting a long cable from a third party, or whatever else their specific situation dictates).
