I remember a similar case on Malta, where I went up a hill to get a nice view from a cave, recommended to me as part of the tourist route. The whole access to the cave lies across private property and there's about 20 signs explicitly pointing where to go and what will happen if you go anywhere else. I got to the cave, enjoyed it, got out, never once stepped outside the designated route. I imagine the owner worked out that meticulous path a while ago to minimise tourist noise.
My understanding has been that every other country has much more "common sense" than we do in these matters.

Needless to say, this doesn't work well on the stubborn, hardy types who'll spend hours ascending hills for fun - but it might deter the more casual walkers.
The local farmers generally detest ramblers, as it’s not unusual to find picnic leftovers, balloons, condoms, whatever, in a field with livestock, so I can understand their desire to discourage walkers. Heck, where I live most of the time in the wilds of Portugal, I initially had no reservations about people using our land to access the river - until they started leaving trash and faeces around the place. Now we have no trespassing signs, which saddens me, but I’ve picked up my last pile of shit and toilet paper.
Land owners have a responsibility to keep the routes accessible and I think they are paid a small amount for it. Grants are available for gates etc. That said they are rough routes so are fairly muddy at this time of year. I love them and base most of my running around them.
