You set up a false equivalence by equating monopolisation with outright coercion when in fact there are multiple types of soft and hard market power that define the degree to which a company has a monopoly in a given market (network effects for example).

Even where market power is not being overtly used to stifle competition there are strong and well established economic arguments for why the breakup of large incumbents can be net beneficial.

Regulation can also cut both ways - one of the main advantages enjoyed by large incumbents are barriers created by regulatory capture (e.g. regulations like GDPR) - small businesses simply do not have the resources to comply and remain competitive. In a sense all regulation has an element of picking winners - to dismiss it on this basis is foolish/disingenuous and completely mischaracterises the debate.

The point is to realise that corporations are private/public institutions and there is a trade-off in interests between the parties involved. Regulation is the art of balancing these interests at the socially optimal level.
