The point is that the Constitution is largely meaningless, feel-good fluffery that has no actual bearing on which of our so-called rights are actually available to us.

It's an aspirational document in a largely lawless land, more a historical oddity than the supreme anything. If you wait for legislators and law enforcement to fix personal privacy, you've already lost... the US law enforcement culture is actively hostile towards individual rights because it makes their jobs harder. The only real difference to, say, China, is that we like to pretend otherwise. But the reality in the ground is that nobody on the grid has had meaningful privacy for decades now.
