Other viable revenue sources must include, and I mean this seriously, having a full-time job and doing podcasting on the side.

Something that does not generate revenue (easily) is often referred to as a hobby, r&d, or fun.

I'm much more interested in the podcast that is made for fun, than one made for profit.

If you end up producing value to others with your hobby, and you decide to ask for value in return, by all means, do so, and provide a non-de-platformable method of compensation.
