In the realm of ideas, everything is possible, but in practice, reality prevails...

Reality is objective and, more broadly, deterministic. Human will is always subject to the criteria of reality.

Therefore, there is no point in believing that everything is possible, as if you could fly by jumping off a building, because gravity will soon come into play in the quickest and most direct way possible.

There are literally universal constraints.
