Why aren’t such things left to the users to observe.
When I buy a kitchen knife, I as a user have to take care to use it for cooking and not for killing people. The knife manufacturers are not obligated to produce knifes that cannot kill humans but can cut food.
For me it is same with hardware. The hardware should be flexible and free. And if the state requires GPS, then it should be responsibility of the user. And if the user does not comply they can chase and fine him/her.
