VMs are free and can be run by any semi-competent developer wanting to host a test server on their development machine.

Postgres and Redis can use non-privileged ports, so I don't understand why this would matter.

"Just use a VM" instead of running a Unix command that drives a UDP socket is... a take.

imo a bit milder of a take than "just maintain a second TCP stack instead of hosting on a non-privileged port".

Also are we just ignoring that you pretended VMs were expensive to run? Most of your responses sound devoid of a lot of fundamental computer knowledge(networking and otherwise).
