Sometimes, rather than explain all the issues (and there are many!) that
you will encounter trying this method, I think it is better to just give
someone the tools (with a warning), and let them discover all the
problems for themselves. People are often set in their ways to trying to
achieve something, and the only way to convince them that it is not good
practice is to give them the tools to attempt it, and let them discover
why it doesn't work as they expected.

Yes - that is the best option.
