Nobody forces the farmer to expand. If he does so it it is because the economy or changing business financials or peer pressure brought it about.
Wall Street forces publicly traded compamies to expand because WS assigns little or no value to stable businesses or low growth companies that make a realistic return on investment year after year.
I know lots of very profitable, very stable, very wealthy business man that do not expand. They run their business to make a living and a profit and they don't give two hoots how Wall Street values it because they have no intension of selling it.
So if you are getting pressure to expand your farming operation, maybe you have been listening at the coffee shop, instead to the radio on the tractor.
