I am not quite understanding why gear can be in our bag and yet we are wearing it at the same time. So it is in two places at once? >.> I think SE should make it so if we equip something it should no longer be in our bag and in our hand/body etc at the same time.

Make it so gear is only in one place please, it makes more sense! I remember in Lineage, Aion etc whenever I equip an item it no longer shows as being in my bag but it just shows it being on my character. I hope this makes sense.
