How feasible is the purpose of Buddhism? (Please read on... not trying to criticize merely curious)?

detachment doesn't mean you can't have desires or be happy or eat food. it means don't be control by it. one is still empathetic and compionate, but not controlling, extreme kind of way. being detached means it makes no difference if only have 1 dollar in your pocket or a million because you have no desire for money. you are at peace with yourself because the world could be spinning, but you aren't spinning in it.
