I believe everything has to be in balance for an idea to work, like supply and demand. Nobody is going to want electric cars if the cost of buying and running them is prohibitive. ( sorry I mentioned electric cars don't get too hung up on that example )
It follows that if you are given a privilege to walk over someone else's land ( I know there is issues some will have with someone owning land but that's a reality here like it or not ) the owner / caretaker needs at least some reassurance that the walkers are going to or are at least asked to treat the land with respect.
There will be the odd nutters who believe everything belongs to them and this world owes them something due to the fact they exist and have the right to treat it whatever way they want so to counter this problem some assurance needs to be given to the land owner or body who has the responsibility for the land, hence giving some balance to the equation.
