Home chargers will always bring in privacy and safety concerns.That said, I still think there's a lot of merit to having a dense, distributed network of home-based charging stations available to the public; I'm a big believer in the PlugShare concept. Of course, the ideal, shared charging stations will be those that can be reached without the host having to open up their garage.
IMHO we should lobby to transition the whole infrastructure out of public L2 charging and into three layered model:
1. Home charging as the base of it all. I believe car manufacturers are neglecting that part but not stressing hard enough how important on overall EV owning experience is the ability to leave your parking spot with "full" battery every morning. By parking spot I mean the spot you keep your car over night. This limits situations when you need/want additional charging pretty much to two cases:
2. Daily commuting when you might need/want to recharge at work. This can/should be taken care of by widespread availability of L1 spots (regular outlets). Even US L1 (1.2kW/h) provides enough charge over 8-9h you're at work to completely cover your commute. And installing electrical outlets is dirt cheap compared to even basic L2 stations.
3. Long distance travel - this should be covered by DCFC station at gas stations, rest areas/oasis and supplemented with L2/L3 at hotels and other overnight staying places.
When I travel I don't want to be searching for somebody's house somewhere 10 miles from the interstate that will take me 20 minutes to get due to 25mph speed limit.
When I go visit friends - I leave my house with full charge, don't want to start the visit from 'sorry, can I plug in?' or 'hey you're neighbor is plugsharing, I'll be right back, just have to park my car there'.
