Certainly true, but for the average user probably not a practical alternative. The larger overall problem here is not technical, but political. Until the composition of the Congress is changed from an anti-Bill of Rights majority to a pro-Bill of Rights majority, we won’t be able to get the changes in law — and the enforcement of those laws — that ensure every citizen is truly “secure in their persons, houses, papers, and effects, against unreasonable searches and seizures…” per the Fourth Amendment.
