But the availability is what matters.

If I want to make an ISP available to even just a small neighborhood, we're talking tens of thousands of dollars of investment. Scaling it up so an entire city can use my ISP is an investment in the millions of dollars.

If I want to make a new eBay available to the world, it's a couple days of software development for a proof of concept and a few dollars for a VM in AWS/Azure/GCC. Polishing it a bit and scaling it up is only a few more months development and possibly a couple thousand in server costs, which your revenue would be scaling nicely with.
