The whole (over)insistence on using the determiners in general seems to be a relatively recent innovation as well, the articles being a large part of it. I am talking about constructions like "he shoved his hand into his pocket and pulled out his wallet" — why not just "he shoved hand into pocket and pulled out wallet"? The context is pretty self-evident, and if you really need to specify some deviation from it (he shoved his hand into someone else's pocket, but still pulled out his wallet), you always can do it by, you know, using the determiners; except now they actually will be non-redundant.

Indeed that begins to sound like so called caveman talk. He shove hand in pocket and pull out wallet.
