I think this is right. It is possible to sell on your own site. Luxury goods do it right now. For example, if you want to buy perfume directly from Chanel, you cannot do it through Amazon. My sense is that Chanel wouldn't give Amazon product even if they asked for it.

That said, I think this approach is best combined with voting for and supporting candidates and social movements which will break up big tech and/or socialize their assets.
