True, and it will never be 100% because society and governments have their own way of pushing back eventually. But as I said, the issue is in the broader strategy, a trend has been emerging for some time now. The cost benefit is subjective so people have different tolerances - but some, like me, exited a number of stops back when they saw the track ahead. I'm only here to suggest others might want to pop their head out the window and decide for themselves.
