$this->bbcode_second_pass_quote('pstarr', 'I') challenged you to name one agriculture system in the world today that is not utterly dependent on fossil fuels, primarily diesel. Until you do so then Liebig's law remains valid.
Liebig's Law is only valid for elements necessary for survival. It has been appropriated in a larger sense for oil, but this is incorrect, as it is not an element necessary for survival. It's an energy source. The question (as you say) is whether we can have a sustainable source of food globally without this energy. However, by admitting this, we are no longer talking about Monte's scientific proof that we're in overshoot (purely because we used a phantom energy source), we're discussing whether it is possible or not to maintain the world's population. This then enters the debate about carrying capacity, which is not cut and dried. Again, I'm not saying that we haven't exceeded carrying capacity (like everyone here, I don't know), I'm just saying that the fact we have used oil to get to where we are is not a reason in itself to say that we are in overshoot.
$this->bbcode_second_pass_quote('', 'W')e have commandeered a one-time planetary nutrient, petroleum that has allowed us to drawdown many other essential nutrients, and it remains simpleminded cargoism to suggest otherwise. Thus dieoff is real. period. end of discussion.
As I've said before, if we had discovered and utilised oil when there were one million people on earth, and used it up when there were 5 million people, we would not necessarily have exceeded carrying capacity, despite getting to the higher populate thanks to the oil. The same argument is applicable now. It is not a proof, although it may be seen in hindsight that we have exceeded our carrying capacity (with the added pressure of the progressive degradation of the environment).
"potential solutions" etc.
are mere rhetorical devices designed to convey doubt, and to reassure yourself and you assumed listeners of your comfort. But there is none.
