It is all about consent. You can give your phone number to a person. Doing so, you should know that he can give it to someone else, anyone. And you shouldn't be surprised if he did. If you expressly told him not to share it with anyone else, then you would expect he would never do it. If he did, you could expect reparation since you had a contract, even if it is only verbal. But if it is really important that your phone number is not shared with anyone, then a contract is not enough: you need to make sure that the person will be able to fulfill his engagement. It is one thing to promise something and another to honor it. You have to established a trust relationship before engaging with someone else. If that person is a dear friend you know very well and have great confidence in him, then you may not even need to tell him not to share it: Your relationship will be so important to him that he wouldn't dare risk it. But you cannot expect such an implicit contract with a stranger.
If you took data from a store without their consent, or you use it for other purposes than what they gave you permission for, then yes they will prosecute you. But you can do the same as well. The thing is that you probably consent to a lot more than you care for, because you badly want to do business with them.
You don't have to consent to anything, nobody forces you doing business with anyone. You can also request any restriction you want from any business you want to deal with. But they also have free will and can refuse doing business with you under your terms. That is just fair.
You can bet that doctors will take great care into not revealing info from their patient records, because if they did, they would loose all their clients. The 'people' can have the power, but they need to claim it.
There is also the case where people just post things publicly, for anyone to see (like here on PF). You can't complaint afterward that someone used that info for their gain. And you can't shout to the world something, then say «Please, don't use this against me».
Amish people don't care about Google. They still have jobs, eat 3 times a day, have a place they call home, get married and have children. In short, they still live a full life.
