Wait are you not American? Have you been following what the conservatives in America have been doing?
They’ve taken any common sense rule and stretched it to the breaking point. And after Roe v. Wade was struck they’ve made abortion completely illegal in large swaths of America.
They have several ways to find out. They’ve mandated hospitals to report any they find out about with stiff penalties for not doing so. Doctors are liable for 99 year prison sentences for performing one. Anyone can inform the police if someone they know is suddenly not pregnant anymore. Anyone can sue a former pregnant woman and she cannot get her legal fees paid for even if she proves it was a miscarriage. This all includes penalties for getting an abortion out of state.
Before Roe v Wade was struck they passed law after law to make it as hard as possible to get an abortion before the 22 week cut off. Including waiting periods meant to artificially delay things and run out the clock and closing down places you could get an abortion until some states had only one or two clinics in the entire state. Then they also funded “pregnancy crisis centers”, whose entire purpose was to obfuscate the entire process.
So yeah some people want no legal restrictions because the conservatives have proven they can’t be trusted with them.
