Mr. wise, what has inflation done over that same time period of the past 100 years? RE over time, with interest, expenses, repairs, etc does little more than match rate of inflation. You think the population is increasing? Birth rate is in decline for several yrs already. Have you heard of the baby boomers? Yes population will be flat to decline for decades to come as they die off. You say prices will never be lower again... and what do you base this off? We still have a ton of deleveraging of debt to do, interest rates are heading higher (especially when the fed stops QE), population is NOT growing, hedge funds are exiting the residential RE mkt (which is a big part of the push up over last 2 yrs), china`s major RE bubble is set to burst in the next 1-2 yrs, and on and on, you are clueless as to the risk out there.
The US population is growing faster than any other industrialized nation. The current population of 316,311,000 is projected by the US Census bureau to increase to 439,000,000 in 2050.

What you don't understand about the babyboom issue (and so many others don't understand) is it is only the birth rate declined after the baby boom generation, and not the overall population. So the rate at which the country was growing slowed. Now you have many people claiming when babyboomers retire, and die we will lose population, social security is going to implode and many other dire predictions that might be possible if the nation's population was declining, will come true. But they simply do not understand the basic fact that the nation is still gaining population and will continue to do so even after the babyboom generation dies, and that this fact alone means all those dire predictions are simply based on a false premise
While real estate does cost money over time, renting does not build equity. So given the choice between paying $1,000 per month and building equity so you eventually own your home outright and paying $1,000 per month and not building equity, there is only one logical answer: buy your home. This may not be the best choice for everyone, due to other factors. But if other factors do not argue against it, buying a home is better financially than renting.
As to land prices never being lower, that is because (as you correctly perceive) we live in a monetary system that depends on inflation, and to a large extent inflation depends on population growth.
So unless and until the nation's population starts to shrink, the economy will continue to be shaped by inflation, and prices for commodities and assets like land and other real estate will increase over time.
The real question is whether the rate of increase of value of land relative to other things, like commodities or stocks and bonds, will be faster or slower. And that, sir, is anyone's guess for now.
Regardless of the relative rate of growth, we are recovering from a crash, and as is true of any asset, it is best to buy it while the price is low, and sell when the price is high. I think it is safe to say the price of real estate is low and for that reason alone it is a good time to buy if you are going to buy real estate.
