It's not illegal for me to drive from New York to San Francisco on Interstate 80. But if I were able to endlessly duplicate myself and my car, about a million of me could hog the entire country-wide highway. Not sure if even that would be "illegal", but it would sure be annoying, and I suspect there would need to be laws updated / rewritten to account for my ability to duplicate myself without limit. I doubt society would just agree, "yep, one of you on I-80 is okay, and so a million of you on I-80 is also okay."
