To tackle the problem HIPPA tries to solve, that is making sure that data sharing is secure and only with the intended parties, I want to see stronger enforcement of liability. Granted, the US doesn't have a great track record on that, seeing Equifax get away with what their doing. But I think that's the system that needs to be improved.
Instead of government dictating what "secure" means, different approaches can be experimented with on the market with strong enforcement of liability providing the necessary incentives.
