Historically, you could always own the corner store, and always get business from at least your block. However the trends driving the "jobless future" will see local businesses absorbed into larger entities. The corner store will be replaced with instant delivery.
So you have to find a niche that is global, and when you find it, you'll instantly be bombarded by global competitors, and you'll have to grow or die.
In the "jobless future," individualism looks like etsy--super-niche artisan work for the status of owning something unique. Handmade luxury items can't replace an entire economy.
