Simple economics. Think about it:
Most folks can get into the stock market at a pretty reasonable price ($100 or so if you open up a DRIP account). Even full service brokerages will take you with a mere $5k to $10k.

How many real estate properties can you buy for $10k?

How much work does it take to sell your stocks and how quickly do you see the profit? Compare that to selling a piece of land and seeing the profit.

You might have a painting that's worth $1,000 ... but if it's not selling that capital is tied up and isn't really gaining anything. You'd do better to buy 1,000 glowsticks and sell them at a festival for $3.00 each... you'd get an almost instant return and can triple your money in a weekend if you've got the right market.
