There are a number of differences. First is that road rules apply to public roads. Private roads have far fewer rules. You might not be able to endanger a child or have duels to the death, but there generally aren't speed limits at all regardless if tools are involved.

Then there is the matter of why the laws exist. Generally they prevent harms, and if the limit is on a tool it is only because humans can't do the harm without a tool. A limit on noise generally only limits the use of tools, but if a human was able to break the limit without a tool then the limit would be applied to them. A law might not have been created yet just because it isn't a threat.

In this case, humans can already copy artwork, so there are already limits in place. In this case the tool doesn't really allow for anything new that couldn't already be done with money. If I could afford it, I could hire thousands of artists to create work in a similar art style up to the limits of the existing law. Such expenditures are rare, but are they something that needs to be limited which hasn't due to being too rare? If not, then why does a tool lowering the cost change the limit?
