This is going to run into several legal hurdles at the State level because Tesla is not a utility. In some/most States only regulated utilities can re-sell electricity.
I say put a limit on Superchargers within 50 miles of where the vehicle is parked on a regular basis. Not parked occasionally but regularly and put a very high cap on yearly usage.
The person that drives 100k plus miles a year using the Superchargers 90% of the time even if away from home is also abusive.

The more time I spend on here the more unsure I am about buying a Model 3. It was my dream, but comments like this, drive trains exploding frequently according to historic posts on TMC, production delays and unwarranted emails being sent to people who don't even use Superchargers is turning me against this company. I travel very long distances for work purposes (Medicine Hat and back a couple times a week - 600km in a day) and if somebody on here or the wing walker Musk is going to tell me I can't supercharge then all the best - I will be buying an ICE. So I will be monitoring things. If there isn't a plan in the next year, my sale goes elsewhere. I don't need the hassle or to be made to feel like a criminal.
