As would having permit lotteries or guide requirements for certain areas that a would be particularly vulnerable to over-use or excessive traffic. A good example is the Cascades in Washington state. Anybody who's ever been there knows that the Snoqualmie Pass area just East of Seattle is frequently a crowded shit-show, but if go just a little farther North or South there are miles of trails that are frequently completely unoccupied. Keeping the Instagram crowd in that one area leaves the rest of mountains largely untouched. Also in that same range is the Enchantments, which is a series of alpine lakes that are legitimately some of the most stunning scenery in the US. The USFS only issues a limited number of permits each year to camp there via lottery, so it deters normies and becomes a brass ring to more serious /out/ists.
It's not a perfect system by any means but it works pretty well to balance recreational use with conservation and maintain people's interest in public lands.
