This objection applies to essentially every warrant application. In this case, the answer is not only, "yes, in part because people are stupid enough not to destroy evidence, and in part because there are plenty of judges who would be happy to be woken in the middle of the night to rubber-stamp such a warrant at a moment's notice", but also "yes, and the court agreed", and "it doesn't matter, because the police not being able to do whatever they think is best whenever they think it's best is the whole point!"
