The capitalist wins because he can sell the same milk cheaper, because then each farmer don't need own truck, and to bother with going around selling stuff to people. Capitalist will have a fleet of cars, sales team, etc optimized for cost efficiency.

Cheaper food means for example - people who couldn't afford to go to vacations, or to buy a computer for their kids - can.

So - designing the logistic chain is worth it, it provides value for customers.

Same as making software.

The design process/writing software on the other hand - is hard to do on big scale from scratch. I'm not aware of any big logistic network that started big.
