You most certainly heard about a thing called "law". In short, it's a paper that limits actions of everyone, including the government, to some known safe subset.
Arbitrarily breaking the law, that is, limiting the so-called "rights" of people, is considered bad, that very law prohibits it. You cannot just go and prevent somebody from doing a thing not prohibited by the law, such as carrying an iPhone, because suddenly you realize that you need to grab the iPhone and split it to pieces to make the world as a whole a better place.
Same applies to other properties, like companies. Unless owners of these are breaking the law, you can't grab and split their companies, because you consider it a greater good.
Of course, there were numerous examples when people ignored law and did arbitrary things, because "revolutionary conscience", "divine right of kings", or just plain having a gun as an argument. While merits of these options can be discussed, they all are incompatible with "rule of law", let alone "democracy", that many hood dear and consider the very soil on which the economic prosperity has grown.
