This post is clearly political and calls for universal health care have been around for decades.
You just need it to become the norm for employers not to provide healthcare insurance.
So for example (and I am NOT saying we should actually do this) if they would simply pass a law forbidding employers from including health coverage as part of their compensation packages, then everyone would be buying their own insurance (on exchanges or wherever) and startups along with every other business would be relieved of the burden.
Before the ACA removed restrictions of pre-existing conditions, merely switching employers carried the risk of losing access to necessary healthcare.
But there is a difference between politics and policy. The effects of various policies and how to construct policy to achieve a given effect are topics that will be of great interest to most hackers. Hacking society is what legislators do all day long. That's why you see stories like this one getting upvoted.
