when someone rejects the demand, it doesn't mean it's worth more, unless there is someone else willing to offer more. But you're dead on that it's worth whatever someone is willing to pay for it. "worth" is a tricky word. We default to thinking that all things have an intrinsic value, when really nothing does. The value of something is only equal to what someone is willing to do to obtain that something.

People think gold has this intrinsic value, but does not either. It's "natural" value is also soley based upon the demand that is put upon it. The fact that people find it beautiful, and that is a great conductor of electricity, are things that are desired about it. And so the more people that discover the uses of gold, the more demand grows.

If there were no googles, or apples, or yahoos, or any of these huge companies with really deep pockets, then there would be no one to offer $3billion for a company like snapchat, and there would be no way it could ever obtain a "worth" of 3 billion. Because, again - anything is only worth what someone is willing to pay (or do) to obtain it. Even your job.
