The examples you've given are of a regulatory system that has been captured by private interests.

All regulatory systems are captured by some interest whether it be private corporations to families to ideological groups.

These are the interests that need regulation, they have turned on its face a system that is meant to protect the people from them and are using it to protect themselves from consequences of their own exploitation. Regulation isn’t exploitation by default.

Hard disagree. Regulation by it's design is meant to change something and with that change something will be made to have a disadvantage.

Exploitation happens when regulation is written in ways that entrench incumbents or erode civil liberties.

That's what regulations do.

The solution is not to get rid of all regulation,

It is the only fair thing to do, all other options are about trying to create equity and usually failing at best and making it worse.

it’s regulation that constrains power rather than concentrating it.

Not in practice. This isn't a recent history thing either.

Your examples are a symptom of what is wrong with the current system, not a demonstration of its function.

Ignoring reality doesn't make thing right though.
