“Very poor analogy about power companies”
You’re going to have to do better than that. Explain to me why it’s a poor analogy.
No industry exists in an absolute state of a free market, nor does any industry exist that is purely monopolistic. All industries lie somewhere on the spectrum. Basic commodities lie on one end of the spectrum. Power companies lie on the other end. But there are options. One can simply do without electric power. Or one can buy industrial batteries or a generator to supply ones power needs, both expensive options.
You NEED power for your life
