You're right, you can go in and reset that field. You can also patch systemd to ignore requests to update the field. Nothing stops you the individual from bypassing the law.
The nasty part of the law isn't that a technically minded person can easily circumvent it. The nasty part is that you have to circumvent it and a lot of people likely won't. You circumventing it makes you stick out more than if you just leave it in place as is as the majority of people won't be doing that.
The point I and others are making is this is a law designed to track individuals and it only ramps up from here. And with this being the intent of the law, it's really only a matter of time before "sudo vim" becomes an illegal act. (or an act these governments attempt to make illegal).
but nobody is tracking anyone yet. The API is not yet in place, in fact there isn't even any idea on how that API should look like. This will likely take a few years to finalize (if ever).
Right now this is just one more field in a database (config file), nothing more and nothing less. Claiming it's the first step to "making sudo illegal" is quite a large stretch, don't you think? If that were the case, Windows DRM, Denuvo, and all those would also have been "the first step in making sudo illegal". Remember, circumventing DRM is against the law for ages now
The FBI for years has had teams of people navigating forums and derailing discussions. The people doing this are paid. Assuming you aren't a fed, you are not paid. Respect yourself and don't do their work for free.
It's in both the Colorado and California laws.
