Not an anthropologist - but instead of "How farming promotes inequality", I'd frame it as "How resource-producing capital promotes inequality". It could be livestock in a migratory herding society, or boats and nets when those were critical for fishing, or whatever.

> In contemporary Western societies, unigeniture is either considered wrong or is illegal; we no longer differentiate between legitimate and illegitimate offspring...

At best, those are common ideals in Western society. Try talking to an old attorney who does family law.

Also worth a mention - in primitive conditions, polygamy can speed the spread of highly beneficial genes through the society. The textbook case is immune system genes - historically, disease killed a lot of our ancestors.

TFA talked about the difficulty of division, and waved at the idea that farming was different from pastoral societies because of the ease of division: farming land is more valuable as it is concentrated (because of the well known dangers of having many very small plots that are difficult to work and improve) but a herd (or fishing tools) can be split and merged far more easily. So agriculture drives to unigenture.

A blog post like this is mostly hand-waving at complex ideas, but that was her argument for it.

I agree, but nitpick: capital by definition can be put to use to produce or gather something. So resource-producing capital is redundant.
