Agreed with everything you and OP wrote until your very last line:

“ If your company needs you beyond that, contract billing should start at 5x your salaried rate, 20 hour minimum.”

Now that’s being a dick. Looking out for yourself does not mean being a dick.

This is not being a dick. Before I left a certain job, I had my supervisor (also owner of the company) tell me exactly this. She once quit a job and did exactly this. And was proud of it. Even if I'm happy I no longer work for her, she was completely right about this move.

Your supervisor was once a dick, and proud of it, so it is ok for you to be a dick. Think about that.

That's what I did and a previous employer occasionally has me do some maintenance work and are glad to pay that rate, especially if I get on it quickly.

Hey, if they’re willing to pay that much for it; charging any less is charity

I don’t know your situation, but it could also be construed as blackmail depending on the circumstances.
