The capital density per square foot is 4 to 5 times orders of magnitude higher than agriculture, to suggest the two compete for land use is utterly ridiculous.
Agriculture competes with urbanization and it will always lose, as it should, because it's not an inherently superior or moral use of land: most of agriculture are ecologically disastrous monocultures drenched in herbicides and fertilizers. A corn field is not a bucolic utopia, but a carefully managed anthropic environment where nature was all but banished for the economic welfare of the rural population.
