It might be true that things like Shopify help to resucitate it, but I'm skeptical. I also don't care about things "feeling" small when they actually vast: this is nothing more than a marketing (de|il)lusion, and does nothing to promote the kind of diversified, distributed form of a resilient, vibrant, equitable and opportunity-filled economy.
We have seen tons of boutique online vendors pop-up however. I wonder how the total diversity compares?
A new age "general store" that was a group of small online vendors getting together (shared ownership) might be an interesting way to resurge local business - imagine like a co-op but for small businesses all under shared physical locations. Products and vendors could even rotate out depending on the season and local population.
Ouch, head outside a major metro area sometime. There's small towns all over the country with a Walmart on one side of town and a Dollar General on the other with nothing but shuttered buildings in between save for the occasional fast food joint.
Walmart destroyed businesses in small towns. They bought up cheap land on the outskirts of town and leveraged their huge infrastructure to undercut all local retailers. The local retailers would be paying Main Street rents with little to no economies of scale. There's just no competing with Walmart in many small towns.
