In short: to hell with this.

When you decide to make it really difficult for the world to engage with you, the world will make sure to make it just as difficult for you to engage with the world as well.
This was mostly referring to the "no cellphone in 2020" scenario, and I hope it is pretty obvious how much more difficult it is to engage with someone who doesn't have a cellphone.
As for how that would apply to the grocery store scenario. When 99% of the stores are automated using similar tech, he would be making it difficult for retailers by (indirectly) demanding them to use cashiers and such, thus making it more expensive and inefficient for the stores. And the stores will strike back by simply not making such stores, thus making it extremely difficult for the parent poster to shop without having to drive far out in hopes of finding one of the few remaining non-automated stores.
But you know what? I’m fine, and I feel a lot better without inviting the behavior manipulation and stress of keeping up with these social platforms.
You don’t have to be an RMS style purist to set boundaries. It’s just a matter of privacy/liberty vs convenience tradeoffs and what you’re comfortable with.
