Even the existing ADA laws do not specify technical details (which is why they are abused in frivolous lawsuits to often).
Your question is essentially "well what if I use a knife, because knives can be used for skinning, which is a legitimate use!".
It doesn't work that way.
In a technical setting, we can't even reliably describe how things will operate 5 years from now. Imagine a law that specified how frames were to operate... and now no one uses frames.
Just imagine a law that says "no tracking". What is tracking? How is it done? How do we know it when we see it? All of this must be defined... and these definitions are fuzzy and change rapidly.
The ADA law specifically says you must make your website accessible... but fails to specify what accessible even means in a modern setting. That's the pitfalls of trying to regulate how things are designed in a technical setting. Perhaps it's possible, but I have not yet seen a good law that made an attempt.
No, actually, don't. I reject everything about your premise.
"What even IS ACCESSIBILITY, OMG, you can't explain that!?!?!".
I mean ... maybe YOU can't, but plenty of people can.
So no, it is not easy to define or describe. There is an incredible amount of detail that must be hammered out to make it easy for everyone to become compliant.
We can also reference the EU's GDPR, or California's CCPA/CPRA. All of which are struggling to actually clearly define what they mean. What is an essential cookie? What does it mean to sell someone's personal data? Neither are what you might actually believe...
You can reject it all you want, but that does not change the reality I'm afraid.
yes?
I can stab my knife into flesh all day, if that flesh is another human being it turns out it's outlawed.
There is no requirement that the law be applied consistently for some action. Insider Trading doesn't imply all trading is illegal. Being able to pop off fireworks doesn't imply doing so anywhere is legal.
