It’s generally not a good idea to be single homed anyway. My first network was only upstreamed by HE and I ran into the Cogent situation quite quickly. Adding more upstreams fixed it. But also other NSPs don’t reach everything. Sometimes there are some niche networks that can only be reached over peering or some other transit providers. Though it’s super rare.

True, but many small businesses don’t have the hardware or expertise to manage multiple full BGP tables. Also depending where you are your ISP options might be limited. For example one of the remote sites I manage only has Lumen/CenturyLink wired to the building. If would really stink if I couldn’t get to anything on HE’s network through no fault of my own.
