Plenty of people get by in Eorzea without killing anything. Adventurers are an outlying minority, and most of the things we see as player-characters do not represent every day life as an average Eorzean citizen because, as ExAtomos said, the game is shown to us through the eyes of the Warrior of Light.
Arguably, it'd be easier to get by as a Sagahl in Eorzea than on the Steppes - there's a merchant infrastructure where you can work for someone, earn money, then buy clothes, grain, bread, fruit, canvas tents, and so on and so forth, rather than having to collect and make everything yourself.
Assuming, that is, that the character was ignorant (willfully or otherwise) of the methods those items were obtained by. xD
(Side note - I assume "animals" definitely means "beastkin" and probably means "cloudkin", but I wonder if wavekin (fish, etc) count...)
