There should be traders who just won't trade with cha 1...
But anyway, I don't think too low stats should have any major negative consequences. Players shouldn't be able to cripple their chars at some areas too much because such person couldn't exist in the wasteland because he would have so much problems with his lacking abilities that he would just die.
Right now anything that has to do with buffing or nerfing certain skills or stats simply encourages alts. Besides cha1 dudes don't buy or sell anything, they just fight. They aren't interacting with npcs in any other way because they don't have to.
how come facilitating barter to char 1 players encourages alts?i have a char 1 characterl with SG 2/ armor 2 and i want to sell /buy without having to go to geck.. also remember the new traveling time
