Keeping your military strong enough is a really important part of the early game in FFH and a no barb/no hostile AI/no lairs start doesn't capture that part of the game.
I'd like to throw out the suggestion that you do this with no AIs, Raging barbarians, and a rule that you can't explore lairs or capture barb cities (though you can raze them). Having no interactions with the AI is important for reducing variability, but if there's nothing hostile out there then that reduces the value of production.
Or maybe you could have no barbarians along with a rule that you can never let a city ever have less than (say) three warriors in it. So you'd need to produce six warriors before you could settle your first non-capital city.
