I think the point was that the real world equivalent of the digital search would not be allowed. It would be considered a vast overstepping of bounds to search 381 houses and do it in such a way that the people that live there did not know that the police broke in and searched it.
I am not saying that real world warrants should be held to the same absurd standards as digital ones. I am saying it should be the other way around.
Digital warrants should be held to the same standard as real world ones. You should need all the same legal standards for each person you want to do a search on and each place you want to search. If searching hundreds of homes is not viable in the real world you should not be giving warrants for that in the digital world just because it is easier.
Terrorism is so rare that it should be handled as an exceptional event within the law and require a justification every time. The information should also be made public after a set period of time to prevent abuse. However, right now the police seem to see a lot of people as terrorists for things that don't involve terrorism at all.
