You're missing the point. No one but YOU is suggesting that these puppies shouldn't be rescued. The argument isn't about saving their lives, because that's what we all want, despite your strawmanning; it's about doing so in a way that prevents even more puppies being bred.
No, you're ensuring that a puppy mill has money and a reason to continue mill-breeding. The pups should be rehomed at the mill-breeder's expense. If you feel puppy lives matter, you would be agreeing with this meme.
