What's wrong with agreeing to signing up to x no of years to offset the time and money invested in training you?

Other places do it, notably the forces where, dependant on your specialization and the level you attain, you agree to sign up for a number of years, essentially so the organisation that spent a lot of time and money investing in YOU, ensures that YOU give some back in return.

Or would you rather have it that (as now) people get trained, get a skill useful elsewhere in the world and fark right off without a second thought because 'it's better for them'

At least with option 1, you still get the opportunity to peddle your skill elsewhere, but not until you've somewhat repaid the time and effort put into getting you that skill. Win win for everyone, instead of having to import dodgy 3rd world, barely english speaking/reading doctors with no benefit for anyone.
