The number of warrants that can be served has nothing to do with the price of beer. Either a judge has approved the warrant based on probable cause presented to him/her by the police, or they haven't.

If the police could hypothetically toss every house in the country twice a day and once on Sundays, that has precisely nothing to do with anything. So long as the only houses they DO toss are ones where a judge has reviewed the evidence, and determined that there is probable cause that tossing the house will turn up fruits or instrumentalities of a crime. Capability to do a thing has nothing to do with approval to do a thing under the law or ethics. I'm fully capable of being a (very bad) male prostitute, but I refrain from doing that for many obvious moral and legal reasons.
