I think that fits into the wider goal of educating people to care for their health for their own good; clearly the methods we're using don't work, and haven't adapted to the world in which you could be doing a million other things. Besides, it doesn't have to be all or nothing, you can easily escalate how much time you spend and plan accordingly. The answer isn't to give up on them.
Most people won't live their lives intentionally no matter what you do. It's a noble goal to increase the number from, say, 10% to 20%. But getting even a majority of people are going to 'care for their health for their own good' is demonstrably impossible. At best you can turn self-care into a game or entertainment, but extrinsic motivation is kind of the exact opposite of the practice of meditation.
