Looking at loads and their impact to distribution circuits, I wonder if we should not ban certain devices?

1) Whole house tankless electric hot water heaters, and allow single faucet tankless or tanked hot water heaters.
2) EV chargers larger than 8 KW, when I posted on the cost of installing chargers at home the vast majority of EV owners argued that larger chargers were not required.
3) Any heat pump that cannot cover the temperature range in the area that it is installed

Should we ban things that cause large demand.
