As I have mentioned before, you don't expect your automobile insurance, even full coverage, to pay for a tuneup. Expecting medical insurance to pay for regular care is just inserting a middleman that extracts value while increasing costs and adding no benefit.
Of course, this means people would have to pay for their regular care and visit the doctor on schedule.
The reasonable alternative is single-payer health care. Insurance is for catastrophic things, not for regular maintanence. Using it to pay for penis pills and birth control only makes it more expensive. Pushing for insurance to cover more things is only making the fees go up and their profits greater. Insurance shouldn't cover your regular checkup.
And, as stated, single-payer appears to be the only rational solution. According to the vast amounts of evidence, it is even less expensive on the whole society AND has better overall outcomes. Those of us with money will still be able to pay for extra care, there would still even be an insurance industry.
