The great divide in civ … or at least one of them. Do you want to play a game where you're forced to worry, right out of the gate, about whether your neighbours will burn down your cities? Or do you want to play a game where you're free to ignore building an early army so you can spend your initial turns on other things? I'm not sure there's a happy medium. Civ 6 tilts heavily towards "win your way", so it might as well focus on that and eliminate the potential for early barbarian overruns. Having the early game offer a challenge when the rest of the game doesn't just detracts from the sim civ fun, without providing a satisfying experience for those who want a more dangerous game environment.
