Getting rid of a toilet might be easy. My trash company accepted one as my once a month “large item”. I just had to dry out all the water and bag it up with the tank and bowl in separate bags.
Upgrading to a modern toilet with a good MAP score was a huge upgrade and not terribly expensive compared to other projects. I think we’ve plugged it maybe once since we got it? The old toilet needed to be plunged regularly.
If you decide to take it on just give your trash company a call first and see what their policies are.
