Like Yang's UBI plan, a whole lot has to be perfect for it to work and even then there's no guarantee.

A few problems I see from a technical perspective:

Telehealth - First there are clinics that already do this to a degree and yes, it has helped bring down costs. Forcing people to do so inters more technology costs, not just initial capital costs but operational costs. Healthcare has some of the worst cyber security out there unfortunately. For instance Our Lady of the Lake just pays the ransom for ransomware attacks (don't ask me how I know, I have on good authority they just do)

This needs to be addressed as well before we start forcing people to have doctor sessions over the internet that could be secretly recorded by a man-in-the-middle attack.

So called Health Deserts - This is the same nonsense to justify government subsidizing grocery stores in urban areas nobody want's to invest in due to high crime. You only have to look to New Orleans to see how bad of an idea this has been. Yang's team assumes rural America has no access to healthcare. There are doctors and clinics in rural areas it's getting people to the doctor. You can't force someone to do preventive medicine even if they get it for free.

Rebuilding EHR - First off, electronic health record systems are complicated and add overhead due to federal and state regulations. Also to include many standards set forth by insurance companies for coding and billing. It's no different than Enterprise Resource Planning software that any other business uses to run their business. That's the nature of it. What I find funny is that we're going to streamline something that got bloated because of government with.....wait for it....more government.

How about EHR companies take feedback from customers to streamline workflow based on their customer's needs. Many already do this and the advances in EHR platforms have given patients more insight into their health records and to keep in constant contact with their primary care provider than ever before, without heavy handed government regulation.

Another issue I see is the whole thing about protecting doctors from malpractice suit abuses. Basically you're advocating for tort reform which has been talked about for ages. With a legislative body that's mostly lawyers and have a lot of friends that are lawyers, you really think that's going to happen?
