Because Germany is a representative democracy where you cannot change the minds of a few elected leaders for at least 3 more years, once elected.

Also, Germans aren't really the kind of people to protest on the streets. They'd much rather complain and complain and maybe change the position of their cross on the next ballot to a party just a small tip further left or right, only to then start complaining that nothing ever really changes and readjust their cross in the opposite direction in the following election. This cycle repeats since about 70 years.

So yes, if the Germans really did not want this kind of stuff, they would have to drastically change their votes. And bear in mind that the current government, which is the most dramatic change (to the left) in the last 16 years since the Merkel era, has already lost the goodwill according to surveys, with people already again favoring the Merkel party (e. g. said readjustment).
