I'm not saying land is a guaranteed money maker (and it probably shouldn't be much more than a money keeper), but to me there's more baseline value there long term. The property that sits on it may fluctuate (in condition, size, value etc), but even if it burns down you have something of value to work with. With condos, you're more tied to the property itself (ie general condition, level of finishings, types of amenities etc), which tend to degrade over time and have to be renovated/replaced. That and more condos can always be added to the market as a city densifies...you can't always add more good land.
My biggest beef though is that so much of condo life comes down to being at the mercy of decisions made by other people. With owning land, you have more control and flexibility with what you can do with it. Obviously there are still neighbours and laws to comply with, but you're still mostly in control. For me, the older I get, the more I value that agency/independence.
