The "people prefer to buy {X} in physical stores" argument rings a little hollow for me. The level of online shopping that happens today would have been inconceivable 15 years ago. And look at what's happening: groceries can be bought and shipped from online purchases. Clothing is becoming more and more online. Hell, I've purchased well-made, good-fitting suits online. And I'm in my 30s. B&N is the only non-indie book store with a significant retail presence, and it's been squeezed mightily as well in recent years. I go to B&N plenty, and there's lots of people. But not to buy books. It's a place where you can buy a coffee and biscuit, work on your laptop for hours on end without interruption, and you don't smell like a coffee shop by the end. Super convenient, but not a great business model long-term imo. And look at how Kindle has destroyed Nooks.
And once current teenagers hit the market in 5-10 years, how much more market share will shift from retail to online with their market entry? Now add in some better quality controls - which Amazon already has in the form of verified purchases and their reviews - and what's stopping us from clothes shopping? Or grocery shopping? Or...anything?!
I'm also embedded in the board gaming hobby, and this is an issue. "Support your local FLGS!" is a common mantra (friendly local game shop). But we all have bills to pay, and Amazon is objectively cheaper for the same stuff. And "board game cafes" are opening that recreate most of what we use FLGSs for (shared gaming space, occasional impulse purchases), but with a more sustainable model that includes legit F&B. So they're adapting and surviving, but it's no longer "retail" per se.
There's a fear that we turn this into "no retails stores" vs. "retail stores are fine" which is of course a false dichotomy. Retail store will always exist. But collectively, they're in huge trouble imo. Toys R Us is getting headlines atm. But the decline in shopping malls has been going on for years. Tech closures are common. And we'll continue to see these announcements until only the "too big to fail" crowd remains (Wal-Mart, etc.) along with local hybrids with a sustainable-but-not-scalable model (like the board game cafes I mentioned, or other indie shops with huge markups but "local" appeal), and online retailers.
