What I said specifically is that INFJ's have some neurotic tendencies and the need to connect deeply with their partners. Yes, I include myself in this. I am neurotic. It's a fact about the INFJ psychology that if we are under stress, we tend towards neurosis. Polyamory is not transcendant nor magical. It is merely different. There are some traits within the poly community that are very different. Monogamy is not any better than polyamory or worse.
Billy, prove to me that people are monogamous. Name ONE culture on earth where monogamy is a norm rather than an artificially imposed stricture which is regularly broken. We aren't prairie voles. Human beings are a massively diverse species with pair-bonding being, if anything, a minority of actual bonding types in civilizations across the globe and throughout our history.
I'm not asking you to name a culture where people say 'You must be monogamous or you're scum'. Heck, you can point to American culture. Name one culture where monogamy is the actual operational mechanism by which relationships function. I've looked. If there is one throughout history in which monogamy has been then norm rather than the public face backed up by lies and deceit or a carefully constructed system to avoid actual monogamy then I haven't found it.
People are not monogamous by nature or for that matter, polyamorous. People are a collective of urges and impulses and sometimes those are directed at individuals and sometimes at groups.
