We often make the mistake of equating money with wealth. Money is simply the currency needed to exchange for goods, services, or assets (which can include securities, commodities, real estate, amongst others), while wealth is control of something of both current and potentially future value to people who will pay for it (see assets previously enumerated, although the list is in no way exhaustive).
For example: Would you rather I give you $100? Or a share of SPY? If you intend to spend, probably the fiat. If you intend to hold for future wealth, more likely the security. And if you intend to be financially secure, you are very likely of the mindset of accumulating assets that will appreciate in value at favorable prices.

People, as a group, undisciplined. Without discipline, money in hand is money spent. Land, land sits there, doing nothing, menacingly. In that sense, land is 'default alive' and money isn't. Generations can go by without any land-atrophy.
It helps with another human weakness too. It's impossible to get a person to save at rates of 30-40% of their salary. But make it a mortgage, and suddenly they've learned conscientiousness.
