Significant impact on RVing!!

Not sure how this is an impact to "freedom". You are still free to go. Covid has impacted a million things, Camping being one of them. When conventional travel became difficult and more people worked from home, people bought campers. This has impacted just about every park, not just national parks. Due to the influx of people, what would you have the parks do? Too many people ruins the experience and to some extent the park itself, not to mention there just aren't enough sites. If you plan on going, make reservations. Not much different than any place else you might go. If and when things return to normal, lots of folks will sell their campers and things won't be so crowded. Until then, it is what it is. But the sky isn't falling and your freedom isn't being threatened. This isn't personal.
