The point is, in the Linux circles I move in, this idea of single file installation would be about as popular as a police raid at a rave club.
This is frankly not true. There are many programs (e.g. games) which are not available as distribution packages, and can't rely on the user's distribution to provide the right versions of the required pieces of infrastructure. Those programs have to bundle the whole stack independently.
Perhaps in *your* Linux circle you never use such programs, but they do exist and are part of the ecosystem.
