being able to express yourself better in vrc, that's the only point of it really. meme erp aside, imagine situation where you want to make a funny cute scene/photo of curb stomping anime girl, but you can't because no legs to move around. fbt is just kind of another level of putting yourself in game, more possibilities, but no clearly defined "function". It's really not necessary at all if you just want to have some fun, don't worry.
