It's not really possible in today's austere political climate, but I think the parks should be free for everyone. Especially as entrance passes to many parks are already rationed, the economic benefits of continuing to charge are relatively small.
My understanding is that’s exactly why access is not unlimited.
Interestingly during the pandemic some Nevada state parks moved to a mandatory pass pre-purchase system as a way to control the number of people in the park at a given time to aid in infection control and prevention. Nevada has some truly gorgeous state parks that are more akin to BLM managed land than NPS land. (To me, it’s all beautiful.)
