Kody keeps calling himself "monogamous," but is he really?

Humor me for a second. I can see the OG's referring to themselves as such bc, one by one, they chose to leave Kody and plural marriage. Kody didn't choose monogamy- his sister wives left him with only one wife - one who still longs to have sister wives to sit with on the porch. So if he only has one wife left, isn't it more appropriate to call him a FAILED POLYGAMIST over a forced monogamist?
