You're arguing with a lot of people who have personally seen this work. You can listen to other people. You can also go to an Apple Store and let them show you what's going wrong here.

Perhaps no one here has tried to download an entire iCloud library at once, or perhaps size is an issue, but that doesn't change the fact that there is no download button for iCloud Photos and iCloud Photos Downloader simply solves this. That's what this post is about.

		I can personally confirm I've downloaded an entire iCloud library at once, to a brand new Mac, using the 'Download Originals to this Mac' option. As have many others here, I would think. That's literally what that option is for. If it's not working for you, you might be dealing with a bug, or perhaps you haven't given it enough time to sync. If you go to Photos > Library and scroll down, it should show you the sync status.

		iCloud Photos Downloader is an option, yes, but it is incorrect to say that Apple does not provide an official way to do this on Mac. Again, I direct you to the Apple Store so someone can show you in person, since you won't listen to anyone on here.
