>20,000 ISP propellent
That is achievable with lithium-fueled electric propulsion. The tradeoff of high Isp is lower thrust at the same amount of power thus slower acceleration, so DFD wouldn't be of much use for most of the solar system. A torch drive could skirt this harsh reality by being immensely powerful but low mass, otherwise, high Isp like >10,000 seconds is vastly overrated.
>Of course, it would also make moon/jupiter mining actually viable
No it wouldn't.
