I have had three full playthroughts in EA and every time I've found plenty of non-magical longbows. There are no longbows in the starting area because longbow is better than shortbow. Should they give you the cream of the crop gear right from the start?
You're making a strawman. The OP never suggested they wanted the "cream of the crop gear right from the start", they simply asked about non-magical longbows. No need for the aggression.
