Great that you actually started reading into the subject :-)
As the linked answer indicates, both #!/usr/bin/python and
#!/usr/bin/env python are valid in different cases, at least on *nix
systems.
Sorry, you apparently misread that answer.
The important sentences are:
"By specifying #!/usr/bin/python you specify exactly which interpreter
will be used to run the script on a particular system."
And:
"I use an installer script that modifies the #! line of each script as
it installs it in my $HOME/bin."
It is perfectly fine not to use /usr/bin/env for a particular system, or
when you write that line during installation. If you do that, then /usr
has no use, too, though, as you already know the target system when you
do that.
/usr/bin/env is, while flawed, a solution to a problem, not something
that became widely used because someone was bored.
Bye,
Axel.
