That's the superficial, somewhat "drink the kool-aid" view.
The charters came in because NASCAR was dropping like a rock in the early/mid 2010s. Viewership, attendance, sponsorship dollars etc all down by as much as 50% in 10 years and no one knew where the bottom was. Charters guaranteed that TV revenue would go to the teams, since that was the only thing that was stable in NASCAR economics.
That's really what it's about. If the sport had not lost its multi-million dollar sponsors no owner would give a crap about a piece of paper stating their racing team was a "tangible asset". No one was arguing for that til money got tight and the owners needed a new source of $$$.
