This seems ridiculous. There should never be a prohibition against a user
doing something that is not dangerous.

If you're worried about this, unalias source after loading this friend's
`library'. You're already changing your environment to include it.

No. If you want to make sure it's unset, force it to remain unset, and
prevent anyone from setting it,

unset BASH_SOURCE_PATH
readonly BASH_SOURCE_PATH

will do the job.
