Nah, it's not an argument but again, roms are not more difficult to find and you don't need to use a site like Arcade Punks to find them either. Sure Nintendo roms are not quite as easy to find but they are still very easy to find without the need for some shady sites either. When EmuParadise and a couple of other sites shut down other sites popped up in their place.
Just for reference, if you want easy to find rom sets just a simple search of the Internet Archive has pretty much anything you want within reason, no modern systems like PS3 or XBox 360.
I know people like to complain about Nintendo going after rom sites but they really only went after one site that was hosting roms on US servers and we're using Nintendo copyright owned media to advertise their site (Mario art work). Other sites that shut down or just stopped hosting Nintendo roms did so on their own volition, not by a threat from Nintendo. Also EmuParadise still has rom sets and roms, just check their forums.
