I don't find it at all absurd. Order-of-magnitude differences in quantity often become differences in quality. It's legal in most places in the U.S. to own a semi-automatic weapon that fires x bullets/minute, but not a fully-automatic one that fires 10*x bullets/minute. It's legal for me to send water into my sewer by flushing the toilet, but not for me to pump the larger volume of water in my sump pump into that same sewer. It's legal for a child to throw a handful of sand from the beach into the ocean. Do you think it should be legal for anyone to build and operate a sand throwing machine that methodically throws all of the sand on the beach into the ocean?
