No, we can't. If we could, we would. Things are like this because we want them to be like this: it's reflected in how we vote. We've had candidates pushing for "Medicare for all", universal healthcare, etc., and who gets elected? The candidates promising to go the other direction. Clearly, American society and its voters do not want this.
Just because Universal Healthcare didn't catch on the first time doesn't mean it's dead forever.
It'll happen eventually. Maybe in 4 years, maybe in 40.
All of that aside, it's impossible to know how much you're actually going to visit the doctor aside from chronic ailments.
don't know how it is in the US, so this may look uninformed, but are you getting extra $$$ added to your salary, equivalent to what the employer was paying for the insurance?
Edit: My wife though pays more for her company insurance as they would need to insure me as well.
Typically people opt out of company insurance because of one of the following reasons: It's cheaper for them to find services through the marketplace (extremely uncommon, but possible), They have superior insurance through a spouse or family member, they feel that the insurance they're provided with isn't sufficient and they would prefer to purchase better insurance themselves.
