Yes, and it’s possible for me to plant lettuce underneath my apple trees and deliver romaine to people in 10 weeks. But the courts can’t force me to do that.

Yes, and it’s possible for me to plant lettuce underneath my apple trees and deliver romaine to people in 10 weeks. But the courts can’t force me to do that. They can force me to turn over lettuce that’s already in the ground. In both cases I “can” deliver a hundred pounds of lettuce to the courts. But the courts can only demand things I already possess. Not “whatever I am capable of collecting”.
