We do not recommend this method if other options are available. It's
rate, but some ports install files in non-standard locations that are
not covered by this rm -rf command.

The best way to uninstall MacPorts without doing the full migration is
only doing step 3 of the migration instructions[1], i.e. just re-install
MacPorts base and then follow the normal uninstall instructions from the
guide. That'll take just a few minutes.
