Capitalism works because companies that thrive take a bunch of inputs and create a product that is more valuable than the sum of its parts. That creates additional value, and in such a model companies have to compete by making better goods and services.

What predatory pricing does is to enable competition purely based on access to capital.

Endless money-losing is a variant of counterfeiting, and counterfeiting has dangerous economic consequences.
