I am an anarchist. I have no respect for legality as the basis for any argument, and I do not trust governments to legislate or prosecute either rationally or morally. Legality has no inherent authority. If the law is incapable of addressing philosophy, is it anything but arbitrary threats of violence?

If we approach the abortion issue as if it were a criminal case, in the sense of "crime" as a violation of the rights of others as opposed to legal dictates, we run into several major hurdles. I do contend that, absent a real medical emergency, abortion is murder. There is a crime because there is a victim against whose life a trespass was committed. Justice requires restitution, but you cannot give restitution to the dead. The perpetrator is the next-of-kin, so the next in line to seek restitution is complicit. I also challenge the presumption that the State has any standing to bring charges, because all governments are usurpers.

That said, the situation you describe in Germany seems to resemble that of Texas law as it stands today post-SCOTUS decision to the best of my knowledge. Abortion after a certain stage is illegal, but the framework for actual prosecution and the nature of jury trial would make it harder to get actual charges to stick.

As for myself, ostracism seems like the most effective tool in communities that might share my core principles. I want to encourage repentance and reformation, not punishment and legalism.

I appreciate your effort at a considered response, and hope this reply is coherent.
