2. Maybe no victimless crime should result in jail time, but there are a lot of penalties for "victimless" crimes (tax evasion, illegal production of controlled substances) that justly result in fines.
EDIT: OK. I typed too quickly with the child support bit. In retrospect, that was a bad example. I also added scare quotes to emphasize that justice can be served in criminal court even if nobody goes to jail.
That argument only works if taxation provides a net benefit to society.
This argument is valid regardless of whether taxes benefit society or not.
You are confusing who is stealing from whom.
How about this one then: At any given level of government spending and borrowing, tax evasion requires higher taxes to be imposed on those not engaged in tax evasion.
Do you have some better examples you would like to use?
Better examples? Practicing medicine without a license (assuming good medicine otherwise). Trespassing (assuming no other damages). Criminal endangerment (assuming no actual harms). Production of controlled substances. Ownership (not use) of unlicensed firearms.
Again, I don't necessarily agree that those are all victimless. The point is that they are arguably benign crimes that shouldn't necessarily require jail time.
