Why can't we buy everything that we want?

Well ... Define "everything"

Money can buy you a lot of things. But if they have a price tag, and can be bought, are they really worth having? We are greedy, we will always get bored with the old and want new things ... So true happiness will not come from owning stuff. "Everything" is a matter of perception: it can be a fancy smartphone, or it can be an actual real person to which you build a connection that lasts forever.
