Yeah. Keep public spaces (meaning, advertising) free of porn, so children who aren’t ready yet aren’t exposed to it and to avoid oversexualisation of society. Aside from that, children who are interested in porn and sex are ready for it, let them explore it with the neccessary knowledge and care and avoid abuse from broken grown ups. Laws should be focused on that, a sensible approach, including the parents. Generally saying “porn only for 18+” doesn’t work, since it’s a primary instinct.
