I plan to live and purchase products for at least half a century more. In that time, it is pretty unlikely that Amazon will continue to be better than competitors, in much the same way that Sears-Roebuck isn't better than competitors today.

Amazon is better for small electronics and other knick knacks, and has an aliexpress with 2 day shipping bolted on, but I do not understand the fear of Amazon retail.
All the other stores have better pricing, product curation, and local availability. They all ship to you in the same time Amazon does.
If anything, having Amazon retail as a competitor to these other retail stores gives customers one more option.
