Afsher, so like Pba you are not really opposed to the city, you are just (perhaps legitimately so) afraid if where it will lead.
As to your question yes if there was an issue if people having brie milah done on their children without their knowledge or permission, and/or people had no idea that their is some risk involved I absolutely would support a law requiring a mohel to get the parental permission (written if neccesary) prior to doing a bris. Who on earth wouldn’t?
