Using real estate as store of value harms society.

When people focus more on making money from real estate rather than providing homes for those who need them, it drives up prices and makes housing too expensive for many, especially in places where there aren't enough homes available for everyone who wants one.
Throughout history, many wars have been fought over land disputes.
This is why it isn't an ideal store of value.

Real estate should be use as shelter and a means for food security.

Imagine a technology where it offers a wealth preservation without polarizing a society.

You know what it is.
