Sure, and that's what anyone into retro gaming or preservation has to do. The problem is that "law" is a legal monopoly on the use of force. So far, the retro preservation community has managed to preserve most of electronic gaming and computing's history up through around ~2010. But only because the technology didn't yet exist to make most 'legacy' digital IPs worth exploiting. There are signs the tacit truce that's existed between retro preservation and rights holders is crumbling.

Interest in retro is booming and Nintendo, EA, Sony and others are increasingly releasing new 'remasters' of retro IP. The same AI tech making decomps/recomps faster and easier for enthusiasts is also shifting the economics of retro monetization for IP rights holders. We can no longer rely on them "looking the other way" and tacitly allowing retro preservation. Rapacious media corporations are determined to squeeze every dollar from the expanded IP rights they paid a lot of political donations to purchase (California senator Nancy Pelosi is retiring a multi-hundred-millionaire). The DMCA and other provisions they bought into law are incredibly expansive. In the past, they had little reason to use them against retro gaming. Now they do.
