Fair question. It would depend on the individual, lots of people would also probably run to their doctors and get increased length/dosage prescriptions so they have some emergency supplies. Younger low income people might just cancel their insurance entirely, those with pre-existing conditions would have to consider employment changes potentially (contractor -> full time) and similarly for those on the marketplace.

Edit: To get on my soapbox a bit here, I think people are being a bit black and white as usual. Yea, you don't need to read every political opinion piece by Fox, CNN and NYT, but you also should read more than exactly zero. Neither of these extremes can possibly be optimal for everyone (or anyone probably). HN really likes the narrative "Title: X is problematic and we should fix it. Top Comment: Well I completely stopped X because it was bad for me and now everything is awesome and I'm a 10x dev!" but it's never really that simple.
