The key is 100% boycotting all services provided by a company. Wikipedia’s list of Amazon product/services as reference (https://en.wikipedia.org/wiki/List_of_Amazon_products_and_services).
Incidentally, I know entire neighborhoods that don’t have other grocery stores besides Target/Whole Foods, not to mention that AWS is the cloud computing industry standard… As a personal example, my vet-prescribed cat foods are manufactured by Purina, a subsidary of Nestlé (needless to say, a separate but also extremely evil large corporation)
I’m sorry, but it’s likely literally impossible for this to be the leading paradigm for 10% of people. Maybe 10% would work but I think it’d already be problematic.
You have to remember that the only reason you got these things was because other people didn’t need them anymore. Why didn’t they need it anymore? Because they bought new stuff.
And you surely didn’t get all these things from a single household. Many different households had to get new stuff so their old stuff became available. It’s likely that more than 10 households are necessary to sustain 1 person that gets everything used, because not everyone buys new things all the time, and stuff often breaks instead of still being fine to use.
I personally would eyeball 1-5% of people could do this like you, but this is just a complete unsubstantiated feeling, a guess.
