Without laws, the people/groups you mention would just use the law of the jungle - might makes right - to get what they want. At least with laws they have to somewhat accommodate this process to get what they want, frequently compromising along the way.
I'm not saying that all laws are perfect, but let's not get overwhelming cynicism get the best of us.
The point is regulations (and laws) are just tools - like a hammer they don't have inherent 'goodness'. A regulation can protect abusive business practices as easily as protect consumer rights.
Might doesn't make right but might writes. (regulations)
As you said, regulations and laws are tools. What you criticise about regulations can be said about laws. A law can protect a vile dictator as easily as protect a helpless citizen.
The problem isn't the laws or regulations, but the fact that we leave corrupt politicians to write them.
Of course, fixing that is much easier than done, because even if you have a functioning democracy, corrupt politicians are still propped up by propaganda. Corporate's wishing to write the laws contribute much to support those politicians with lobbying and propaganda (Murdoch news empire)
To solve this you need a well-educated, politically conscious population, which is easier said than done.
Multiple banks and credit card companies customer support lines now say "this call may be recorded and your voice may be used for identity verification".
I am very skeptical that Facebook has ever acted in their users best interest. The EU privacy laws and the GDPR are a clearly beneficial law to citizens, protecting them against hostile companies.
