That's the problem, the government has interfered in several of these markets, subsidizing one item over another. Look at power generation in California: they drove out nuclear power by subsidizing wind and solar.
I get that some don't care about the future and/or think resources like fossil fuels are infinite....but there is an eventual limit to everything. My thoughts are that subsidies are a combo of PAC influende and perhaps trying to play the long game. Known oil reserves are targeted to run out in about 60 years. Coal there is a bigger buffer (140 years). These measurements are probably not an exact science but promoting a switch starting now seems like a smart risk mitigation to start to ease the burden and shift to electrical where there is a longer lead time with coal generated electricity and as posted, nuclear as well. This will also have an impact to national security.
Note that Lithium supply is projected at 70 years. There are different battery technologies in development to extend life and charge capacity, reduce lithium or provide alternatives even without heavy metals or even revamping traditional solid state batteries.
