Finite amount of gold as well. Finite amount of bitcoin cash as well. Finite amount of real estate as well.
For new real estate, there is also basically an infinite amount that can be added to the market. Planet earth is still mostly unused.

Real estate is definitely not “infinite”. Especially if you consider arable land and weather patterns.
