I think the comparison is subjective and for that reason doesn't really makes sense. Bitcoin, regardless of where you are or what currency you use to acquire it, has the same level of scarcity basically for ever, to anyone.

Another thing is that the location of the land is very important in terms of valuation. 700 acres of land in one country can be 100-1000x cheaper or more expensive in another country. It doesn't have one overall valuation like Bitcoin.

The most important difference in my opinion is the fact that you can actually own your Bitcoins, while with land the government can claim it and you're left with nothing. Bitcoin is an entirely different asset.
