Does something like Google Stacking really work?

Hey! I read stuff about Google Stacking and Authority Stacking here all the time.
I actually checked some of the Example Pages that used the Google Stacking Method only to see the Google Pages not even Index.
Does Google Authority Stacking actually do anything for your Website and Ranking?
Or is it just a way for people to make easy money by creating Google Docs that link to each other?

Actually Curious about it.
I am not trying to throw shade on the Sellers that sell it here.

Imo it's a gimmick, like most other things. Invest your time in better link building opportunities, anything that's available for free on a public platform is not worth the time and effort.
