I wonder why OP thinks doctors would have any incentive to do this. It doesn’t benefit them personally and there is just a vague benefit of lower medical care costs provincially.

It's a job that pays money.

And people can become zealots for what they believe is best for others

This is probably the worst part of living in a lower trust society. We just keep decreasing the bar of "good faith". It really sucks, yet I get your point.
