People give to charity what they don't need. If all businesses are expected to be charities, they cease to be profitable and thus cease to function, as no one will bankroll the initial investment required to set up a business without the prospect of making money on it.
Let's look at an example. In order to produce e.g. wind turbines, a large factory is needed, full of expensive machines. Let's assume that the buldings plus the machines all costs $500 million altogether. Where would that $500m come from, if the factory will never be profitable, so entities with money will never bankroll it? The only alternative I can think of is 100% socialism and centrally managed economy, where all businesses are owned and bankrolled by the state. However, in practice all such implementations so far (over probably at least a dozen different countries) has been terribly inefficient and corrupt.
