If PEP 723 is only an enhancement proposal does it work only because `uv` happens to support it?
Can you not use `uvx` with your script because it only works on packages that are installed already or on PyPi?

I don't think running with uv vs uvx imposes any extra limitations on how you specify dependencies. You should either way be able to reference dependencies not just from PyPi but also by git repo or local file path in a [tool.uv.sources] table, the same as you would in a pyproject.toml file.
You can use uvx run scripts with a combination of the --with flag to specify the dependencies and invoking python directly. For e.g
uvx --with youtube-transcript-api python transcript.py
But you wont get the benefit of PEP 723 metadata.
