I don't doubt you.

However, please consider what your options would be to get healthcare outside of the German government system. If your local hospital was known to be following protocols that only allowed damaging, non-curing drugs to be prescribed and upon admittance you were cut off from any relatives who could act as your advocate if you became unconscious, you wouldn't want to go there. It would be a death sentence.

What would the comparable costs be outside the government system?

Are there any options at all?

Still think centralized medicine is the cure?

Is centralized, monopolized, controlled 'anything' good for the people?

There are many health insurances, not only the state insurance! Which one you choose is your business. If you travel abroad, there is a foreign insurance, i.e. you pay in advance, but you will be reimbursed afterwards. The insurance pays for the drugs that the doctor prescribes, for very expensive meds you pay a share, but it is very small. Of course, you can book additional services, such as return by plane in severe cases of illness, but I do not know the additional costs.
The insurance costs are immediately withheld from the salary and paid by the employer. Self-employed people payy the amount themselves. It also depends on your income.
