Bash can't be made to bind a socket that listens and receives instructions from the internet without also having something like socat or netcat or inetd and there's no privilege-free packaging system to rapidly get there.

Python and other powerful scripting languages can.

Having production servers that don't have Python/Ruby/Perl/etc unless they absolutely must is decades-old advice at this point.

The smart ones take that one step further: no production server should have any binaries that aren't absolutely necessary. This is why we use containers.
