I do not question that production has increased.  That was not the assertion.  The assertion was that the increase was "a direct result of SB21."  It is highly plausible that the increase is a result in spite of or incidental to or even indirectly a result of SB21.  Without some causal link it is plausible that to draw such a conclusion is an exercise of foolish/lazy thinking, ie. correlation = causation.
