A lot of things are "law of the land" but are patently unconstitutional. The Constitution is quite clear that unless a power is specifically delegated to the Federal government, then it remains the sole prerogative of the several states or the people themselves.
The idea that the Federal government should ever have millions of pages of laws, codes, and regulations is anathema to the Constitution that created that government. The Constitution is supposed to function like a contract between the people, the states, and the Federal government. The Federal government is the creation of the states. They instituted it to broker among themselves and with foreign entities. It cannot possess any power not first granted to it by the states and the people. I know everyone here knows all that, it just bears repeating. It's mindboggling how far we have gone from that. Our system of government now seems to operate on a principle of "well Washington has gotten away with it for so long and in so many different instances, that's just how it is and it would be stupid to try and stop it now".
Any contract not interpreted literally and under its original meaning is no contract at all. What's the point of a rule book if it can be reinterpreted at will? Yes, the people do bear a substantial portion of the blame for this state of affairs, for allowing it to happen and for allowing it to continue by reelecting politicians who do this damage. But at some point that amounts to blaming the victim, because so many of them cannot even conceive that it's wrong, that it's a Federal government simply arrogating whole new authority to itself. There is an enormous normalcy bias at work now. People in Congress like Pete Stark are on record as saying outright that the Federal government can do whatever it wants, and numbnuts John Roberts evidently agreed. But just because they assert it doesn't make it so, which leads to the next point.
Everything in politics since the beginning of time ultimately comes down to who can force his vision on everyone else. We contrive niceties and rules in an effort to buffer against that reality, and those contrivances can work well for a time here and there. But what do you do when the rules are openly flaunted? You're then back to the central premise of politics: who can force his will on others? I have no doubt we are on that inexorable trajectory and the question is going to be answered in the same ways that it always has been.
