Most of this is personal opinion and snobbery that I can’t do much about except maybe ask that you examine how anarcho-capitalist your takes sound.
Objectivist, perhaps. They’re the ones who obsess over controlling and monetizing free external benefits. There is no copyright in anarcho-capitalism (including “moral rights” etc.) so the GP doesn’t sound at all anarcho-capitalist while arguing for infringement of others’ real property rights to prop up their own artificial (non-rivalrous) “intellectual property” rights.
The ubuntu:24.04 Docker image is only 77.30 MiB.
alpine:3.19.0 is 7.38 MiB.
Of course those sizes are without a kernel. Typical everything-included distro kernels are generally a few hundred MiB as they include drivers for everything that might be needed, but a custom build for known hardware can reduce that to just a few MiB.
