Not sure what "we" and "plenty of" mean. This is regulated state by state. And the number of laws (?) is irrelevant if they are ineffective. Ohio, for instance, has gun shows that advertise on TV and facilitate casual gun sales. Not even a Walmart, just a booth at a convention center. * Some states have permissive gun regulation. * There is no consistent, nationwide background check system. * There is a large field of options between where we are and "take guns away from all civilians forever". We already prevent the sale of grenades. We prevent the sale of gas. Doing so makes it harder for criminals to be criminals in particular ways. We can similarly restrict the sale of certain kinds of weapons to make it harder for criminals to be criminals, just as some of our other rights are restricted outright or through case law (including free speech, freedom to assemble, and others).
