The crux of this argument and the propaganda the current administration lawyers have been shilling centers around whether these searches (ie, mass collection of US citizen data) are unreasonable. I reject your argument that searches are reasonable because the internet infrastructure is currently fundamentally flawed; as already concluded in Katz v. United States, an unlawful search occurs when a "reasonable expectation of privacy" is violated. Given your own argument, any and all attempts by end users to obtain privacy, via https or otherwise, constitute an individual reasonably expecting privacy and therefore any information gathered is done so illegally.
