So you do agree then that Satoshi drinks your milkshake?
The best analogy I can come up with is this.
Satoshi filled his milkshake, but didn't drink yet because it tastes terrible.
We fill our milkshakes and start to drink. At first they taste terrible, but we keep drinking. Gradually our milkshakes taste better and better.
And by the time Satoshi eventually drinks his milkshake [...] it tastes mighty sweet, thanks to everyone else.
This metaphor was intended to show the symbiotic nature of bitcoin.
We needed Satoshi to invent Bitcoin so that we could benefit from it. But equally, Satoshi needed us to use Bitcoin so that he could benefit from it.
Satoshi could have generated endless bitcoins, but they would be of no value to him unless we were generating and using our own bitcoins. Our actions gave value/sweetness to Satoshi's bitcoins/milkshake.
