That's the beauty of funding it with sales (VAT) tax. No one slips through the cracks.
As is always the case, the truth is in the details.
It depends what you are going to fund with a sales tax.
If you are going to fund full "everything is covered" sniffles to cancer for everyone including illegals.
Then that sales tax will eventually be enormous.
If you are just going to fund catastrophic care then it might be doable.
I think the best form of health insurance is some kind of medical savings account.
With medical savings account reality of costs are brought to bare.
Any system that allows patients to not care at all about costs is just not reality.
And ends up being extremely costly which in turn causes health care rationing.
The patient needs to be aware of costs and have incentives to lower costs.
Medical savings accounts do some of this.
I actually might support a law requiring health insurance
if you have it...you are exempt
if you dont have it....then your paycheck is garnished...like a tax.
