The network emission adjusts to the amount of computational power on the network, every 2016 blocks. So if there was 1/1000th of the computational power on the bitcoin network, blocks would still be generated in the same time span, 10 minutes. If there was 1000x more computational power on the bitcoin network, blocks would still be generated in 10 minutes. If you understood that already then I'm not sure what you or the prior person is referring to exactly. If you mean that all the halvings would happen a decade earlier because bitcoin started a decade earlier, I'm not sure what the point of mentioning that is. If you mean the exchange rate would have been lower, the same scarcity drivers would exist, who knows who cares. The "big miners" would be bound by market forces of what's anything worth to them, and would likely be 100% proportional to today's reality.
