Distributions optimize for software in their repos. Software in their repos is compiled against libraries in their repos, so dynamic linking has no downsides and has the upside of reducing disk usage and runtime memory usage (sharing pages).
Your problem with "libFlac.8.so is missing" happens with using software not from the distro repos. Feel free to statically link it, or run it via AppImage or Flatpak or Podman or whatever you want that provides the environment it *was* compiled for. Whether the rest of the distro is dynamically linked or not makes no difference to your ability to run this software, so there's no reason to make the rest of the distro worse.
I personally do care about disk usage and memory usage. I also care about using software from distro repos vs Flatpak etc wherever possible, because software in the distro repos is maintained by someone whose values align with me and not the upstream software author. Eg the firefox package from distro repos enables me to load my own extensions without Mozilla's gatekeeping, the Audacity package from distro repos did not have telemetry enabled that Audacity devs added to their own builds, etc.
