Real Estate or Royal Estate?

The following is an excerpt from Wikipedia concerning the term "Real Estate":

****************
Some people have claimed that the word 'real' in "real estate" is descended (like French 'royal' and Spanish 'real') from the Latin word for 'king'.

In the feudal system (which has left many traces in the common law) the king was the owner of all land, and everyone who occupied land paid him rent directly or indirectly (through lords who in turn paid the king), in cash, goods, or services (including military service).

Property tax, paid to the state, can be seen as a relic of that system. Some say this derivation is a misconception; but that is countered by evidence that the earliest meaning of 'real' in English included "Of, relating to, or characteristic of a monarch, royalty, or (by extension) the nobility, esp. with regard to power, wealth, or dignity; (also) befitting a monarch."

When you think about it, the sum of all the taxes (property tax, real estate tax, etc...) you pay for the real estate you own during 30 years may be equal or greater than the official value of that real estate. So in other words, the state or the government is still the eternal co-owner of all real estateof the country. The King is dead but Long Live the State!
