What you view as mixed up priorities may not be for someone else. My situation is a little different because we get "free" healthcare, but if we didn't, I certainly wouldn't have $100 a month to pay for DPC. My wife works as a nurse four days a week. Between our two incomes, we barely have enough to pay for childcare for the kids, feed all of us, clothe all of us, keep the vehicles running, pay our cell phone bill (which apparently you don't think should be a priority, and if you don't think it is that's because you don't have kids or a job that requires you to have one), etc.
We have a few things we could cut out, but we'd end up paying more if we did, so that's not really a smart choice. We have a small cushion every two weeks in case something disastrous happens, and paying for all four of us to be on DPC would eat into that significantly.
Think a little outside the box, pardon the cliche. There is a huge population who are not outright poor but could not afford $100+ a month.
