All you need is a ‘no selling electricity today please’ button.
It already has an EV charger plugin, so I'm in complete control of my selling energy back to the grid if I want to use it.
Some of the comments on this post feel like the "government is coming for your guns" level of foaming-at-the-mouth.
Remember the ultimate aim is to use energy more efficiently and reduce our dependency on fossil fuels, not make it pointless or difficult to live life.
There are plenty of scenarios where the EV makes more sense than a dedicated battery for it.
In my case, I live on a very shaded property; no solar for me. I also live next to an electrical substation, so extended outages from storms is highly unlikely; I'm first on the fixed list every time. In my case, the home battery doesn't make sense, but the EV might still.
EVs as grid storage is an option that may be compelling in some areas and for some people. I think that's worth exploring.
