The SALT cap was a penalty and wealth transfer (effectively towards red states) placed by red state congressmen (all the while proclaiming the gospel of ‘lower taxes’) on blue states against their will, and (in the process) effectively raising their tax rates on many of their residents in the process, so your quoting the SALT cap to support your POV seems ironically impoverished. Essentially, you argue for the ‘freedoms’ of red states while referencing a legislative shackle they imposed upon others.
The greatest freedom you’re extolling here is the freedom to attempt to rhetorically mislead others.
