>and eventually build a structure which has no relation to reality

This is a bald-faced lie. Mathematics is an abstraction of reality. It is at its basis. But mathematics is much more powerful - it allows us to model reality without the need for the time or resources necessary to set up the same model as an experiment. Furthermore, it's much more powerful, because it allows us to quantify hypothetical scenarios that would be impossible in real life (for example, what if we had negative energy?)
This such play of abstraction provided much-needed insight. Imaginary number for example, were once a laughingstock— but are now a widely accepted and appreciated concept that is used quite extensively in electrical engineering as well as graphics simulations (particularly, for quaternion cameras and model skinning).
