No matter what dollar value others may claim real estate is worth, in the end it is ultimately limited in quantity... If you own it you can grow food on it and you can build and live on it in a depression At least that quantity remains fixed, unlike say oil which is reducing in quantity. If you want the ultimate long term hold I would have thought something like uranium would be the go, has very high utility, diminishing quantity..
Other bulk commodities are fixed quantity, and can be used to build stuff - which is probably more important than the block of land. The limiting/scarcity factor moving forward is not land (we can always build up, and fill skyscraper units with topsoil and artificial lighting to enable farming :P ), but energy and resources. I'm sure land will do fine long term, but not sure it's the ultimate long term investment.
