By your own market argument, increasing oil supply depresses prices and boosts usage. And NA oil isn't particularly clean or environmentally-friendly - the benefits of local production are primarily political, with a side of cheaper gas, which again, is not fighting climate change with market forces.
And Tesla is not the only game in town for electrification, and it's been like that for years already. Tesla's EU sales plummeted while overall EV share rose quickly during the peak of the 2025 "boycott". Someone who was going to buy a Tesla but got turned off by the Musk-Trump coalition just bought an electric/hybrid from someone else - there is no movement to buy gas cars just to spite Musk (unlike, say, the "roll coal" crowd).
