Its nice as in there is no risk and its passive, but 24g a day is not that much and its 1 large farm taken(and you need to get milk in every 6 hours on the nose or that 24g a day starts to skew). There are a quite a few other things you could do to make that much or even more, with some having obviously more risk.
Hell I could be lazy and just plant a large farm full of single clovers every 1.5 hours and probably make 50g+ a day selling the lucky clovers from them(not to mention other rare drops). But that's boring and its alpha, I don't really care about maximizing gold atm.
