This seems pretty silly. It's a civil matter, isn't it? Has anyone ever gone to jail for violating an open source license?

You could simply choose to not pursue legal action against license violators. Choosing a permissive license and then complaining when people do what you gave them permission to do is just ridiculous.

You can goto jail for not paying a civil settlement. All laws are eventually backed by violence.

No. Willful copyright infringement for commercial game is a crime. See 17 U.S.C. § 506(a).
