There are many other fields that require a degree. Engineering, architecture, chemistry, biology, etc. In some of those fields you can find some jobs which you can do without the degree, but the vast majority do require it.
I hire people and, to be fair, most people with a degree do not qualify as valid for certain jobs. But in that case is lack of knowledge. In my case I'd rather have someone without degree but with a deep knowledge; but those are very hard to find.
How many things relevant in your life are made out of gold? I guess jewellery, computer and phone. Real things that matter to people the most are completely unrelated to gold.
The fact that it is a material that does not degrade makes it a good choice as a vector for value. It is good to be used as money for that reason. If you use iron as money it will eventually rust out and leave you broke.
The other properties of gold are quite irrelevant to the fact that it has been selected (over and over again through history) as a value vector.
