I'll going to pursue "the path of theoretical physics", even if I can't tell a sqare root from a potato... who other than me would be in a position to say my "path of theoretical physics" lacks value?
Physics is testable against real world experiments. If your model adequately explains the experimental evidence, then it has value. That's why people still study Newtonian physics, even though it fails at quantum dimensions and/or relativistic speeds.
But how do you "test" a purely spiritual pursuit?
