The purpose of the judge signed document is to inform the home owner that the invasion is lawful, and he shouldn't resist. Leave out the presentation and inspection phase, and you may as well skip the warrant altogether as far as its Constitutional purpose goes.
It also adjudicates probable cause based on sworn affidavits presented as proof of criminal activity that justifies the breach of Rights as described in the Constitution.
Yep, and equally important, but ultimately useless without the opportunity to inspect and stand down.
