Do you always have to use thin set to mount a backer board to the floor? What will happen if you dont?

The answer to your question is yes. You always have to put a bed of thinset under the underlayment. The reason why, your subfloor is not going to be perfectly flat (like most backerboards) and the two together will cause a gap allowing some movement underneath when you walk on it. This movement will cause grout cracking and tile pops.
Hope I was of some help.
