Trying to understand your point. Do you mean the phrase "but upon probable cause"? And if so, do you mean that it would have been a better utopia if searches were not allowed even with probable cause?
Probable cause is not required for searches. Probable cause is required for a warrant to issue. Searches must be reasonable. Searches without a warrant are simply presumptively unreasonable.
Given that is already in there why add the additional caveat that then allows unreasonable searches? Surely reasonable searches are all we really need.
