I think my point is that the cost of integrating the work of many into a small business are going to drop. I believe (and am probably alone in this belief :-))

I think my point is that the cost of integrating the work of many into a small business are going to drop. I believe (and am probably alone in this belief :-)) that there is still an inherent tax advantage to having everything in one entity that probably outweighs the disadvantages of coordinating a large group. A group of 100 members trades internally without paying taxes on these transactions, but everything between independents has some tax effects for at least one side. If this advantage were removed by some kind of tax reform, I suspect corporations would be smaller on average. Getting back to the entrepreneur, even if there are many standard-izable things in a process, there are costs to outsourcing those things. Automation of physical logistics may greatly reduce these costs, making it possible to focus on just the unique value one can add and be rewarded.
