The reason why EOS RAM is described as "scarce land" is mainly because it has some characteristics similar to land:
Finiteness: The total amount of RAM in EOS is limited, similar to the limited land area on the earth. This limitation makes RAM a scarce resource, and its supply cannot meet unlimited growth in demand.
Basic support role: Land is the basis of agriculture, construction and other economic activities, and EOS's RAM is the basic resource for various applications and smart contracts running on the EOS blockchain. Whether you are developing a new DAPP, conducting transactions, storing data, etc., you need RAM to support it.
Investment attributes: Land is often regarded as an investment product due to its scarcity and potential for value growth. Similarly, EOS RAM also has the properties of an investment product. Due to its limited supply and growing demand, investors are optimistic about its future value-added potential, thus driving up RAM prices.
To sum up, EOS's RAM is vividly called "scarce land" because of its limited nature, basic support role and investment attributes. This metaphor helps people understand the importance and value of RAM in the EOS ecosystem.
