The Netherlands has also a private market like this: https://www.government.nl/topics/health-insurance.

I always go for a high deductible (and lower monthly fee) for example.

Edit:

(1) Costs for individual: It does cost me around 80 euros, my deductible is 800 euros (maximum allowed) and I'm 100% covered for medical costs at the physician and at the hospital.

(2) Costs for government: 11.9% of GDP.
