I think the more appropriate take is that this generation isn't ready for such a perfectly logical mechanic. And by "this generation", I mean in the grand scheme of history. In the last 50 years or so, humanity has become incredibly selfish. The natural instinct to procreate and pass the torch to the next generation has been overwritten by "But what do I want for me and me only?" Some 6,000 years of human history and this is only a very recent thing, hence why I call it "generational", I'm not pinning this solely on Gen X or Gen Z or whoever.
In short, humanity has gone stupid and hates its own young to such a degree that this sort of mechanic was never going to be received too well. But whatever. I'm enjoying building my dynasty. I just wish they'd dial it back a bit on the birth rate. It's an extremely logical mechanic for a game of feudalism. Necessary, even.
(Also, no, I'm not calling the people in this thread stupid. I'm calling humanity stupid.)
