G-d put us in this world and told us to make the Gashmius holy, not to totally stay away from it.
Most mitzvohs are done with gashmius Tphilling are physical so is Matzoh and Wine and a Sefer Torah are all physical things.
You cannot regulate the world into safety not in terms of physical health and not in terms of spiratual health.
People must raise their kids to be healthy and responsible, not try and order the world to change so they can be safe while still being irresponsible, that is not the Torah way.
