Well, yes, but at the the cost of being exposed to a risk which, happily for you, did not eventuate. Had you got sick in that time you would not be up €5,600; depending on how sick you got you could be quite seriously down.
Have you worked out how much money you have lost by insuring your house against fire for the past ten years, and it didn't burn down in any of them?
The point here is that insurance isn't a purely financial matter. If you insure against a risk that doesn't eventuate, the premium you paid isn't a dead loss. You had the benefit of being covered against the risk, which provided reassurance, relieved stress, etc.
Not having health insurance when you're young and healthy (and have nobody financially dependent on you) may be a rational choice, but it does depend on personal preference and values, so what's rational for you may not be rational for me, and vice versa. You may be somebody who, if they do get sick, will be stoical about it; will take what comes calmly; will not resent the loss of time, loss of capacity or loss of earnings; will not feel guilty about how your sickness affects others close to you; will take comfort in the consolations of philosophy; etc, etc. Or, you may be somebody who will bitterly resent every day spent on a waiting list; every minute spent in a waiting room; every opportunity or occasion that you can't avail of; etc, etc. Preferences like that will feed into your decision about whether to effect health insurance or not.
