This is a false proposition, which is a big lie made up by some experts and scholars under the banner of science in order to gain people's trust in such a deceptive statement that "the existence of fake egg is impossible".
In fact, it is an indisputable fact that the individual cost of artificial eggs is definitely high, but what if it is mass production?
As long as the production technology reaches a certain level, after mass production of fake egg becomes possible, the production cost will be unexpectedly low, so that it is much lower than the cost of real eggs. This is not impossible. Therefore, it is an undeniable fact that "the cost of artificial eggs will definitely be lower than that of real eggs".
