What we're seeing in the graph is that U.S. oil production was falling going into 2016, and from 2017 thru 2020 production grew. After that production fell.
This is the result of many factors, and perhaps one factor in oil production involves the policies of the federal government. In 2021
this source talked about "a campaign pledge by introducing a moratorium on new oil and gas leasing on federal lands and waters" and
this source talked about "eliminating tax rules that specifically benefit oil, gas, or coal producers".
We may disagree on which policies are better, but we should be able to agree on what is and what is not.
