You don't need place to keep land. Though land is a by far more risky asset than gold. Internet and Hollywood are full of harrowing stories and movies about people investing in land and then going bust when their expectations didn't come true...
Not quite risky IMO. Actually any type of "investment" is risky. Best thing to do would be to choose one that has less risk than the other. Basically land will preserve less risk than gold though
I've never heard of anyone going bust with gold. Primarily because you can always sell it quickly, even with a discount or at a loss (and since gold is a money in itself). The same is not true with land, you may not be able to sell it at all. Don't take it too personal, but from what I've read in your posts, I can only conclude that in most cases your knowledge about the matter is superficial at best, that of a layman. I, for one, am neither engaged in such investments (I mean land), nor have deep understanding of it, but I do know that land (or real estate, for that matter) is a hell as an investment option...
Indeed you can sell your gold almost instantly but do note that I based this on my experience. I lived in one of the highest population country in the world, where "land" is a better asset than gold. You may live in a country where it is hard to sell a "land" but in my country, if you put up your land for sale, you can expect a phonecall less than 24 hours, much quicker if it is located in an urban area though. That is why I go bust with gold
As per I stated, Gold is not always a good option. That doesnt mean that real estate/land is the better option than gold though
