Freemoney can not buy anything from you since you don't value bitcoin.  He can only get value from his bitcoins by selling them or buying goods and services from people who willingly accept to give that much value into bitcoins.  So it's really not unjust in any way.

As for LTC (litecoin iirc?), I don't know much about this thing but if you think it's better than bitcoin for whatever reason, go for it.
