There are enough large companies who have committed misdeeds worthy of major consequences that if we actually punished all of them in a meaningful way, the economy would fall apart, because there would not be many companies left.
> it would create opportunity for actually well-run businesses that benefits the customer to take their place
This assumes that you have a functional society after say...Chase or Nestle or Pfizer or Boeing or Disney, etc becomes insolvent. You will lose more than a decade in churn as the monopolies (enough that they can dictate legislative agendas) leave huge gaps that are inevitably filled with instability. The "good actors" that would backfill is a utopian fantasy. Different names, different brands, but the same kinds of people would end up in the same positions of influence. That's how the (mostly) capitalistic system operates.
They dont need to be good, they need to have real competition and realisation that is they break the law they will be slapped hard
Also, we wont have functional society without Dysney and Nestle? What, society will collapse if we run out of chocolates and movies? People won't have diabetes?

The breadth of these companies is almost immeasurable. Nestle owns an immense amount of resource rights (eg the largest siphon of natural water from the Los Angeles basin) and industry (#1 food producing company in the world). Disney is the leading intellectual property holder of the world. The ubiquity, innate cultural knowledge, and economic strength of corporate entities in the world are part of what keep society stable. The brands are stable, so families are able to be stable and confident about the future.
This is why I picked out examples from multiple industries, all of which are known actors, who have been slapped on the hand for heinous acts over recent time.
