Lead has been known to be a health hazard for more than a hundred years. The government rules limiting lead were applied to corporations and the like - they defended some people from harm done to them by others. But government has grown more intrusive and meddling and authoritarian in some ways, - and blaming the victims for governmental abuses is a shameful way to argue. When the rules are imposed upon individual people to constrain their own management of their own lives, that is different from when they are imposed on corporations to prevent them from harming others. It's basically the "consenting adult" standard - and apparently just as hard to get through to an authoritarian.
