I'm not sure who or what you're arguing against. It's a good thing when fuckup companies are replaced by better ones; that doesn't mean it's a good thing that companies keep fucking up.

Tangentially, publicly-traded companies are strongly incentivized to keep growing at all costs until they collapse under their own weight, rather than just finding a market and serving it well year after year. I dunno if capitalism is to blame specifically, but it certainly seems perverse.
