However, a lot of patent holders do offer licenses. They often charge a lot of money for that though. The company licensing the natural order recalculation patent was demanding 5% of the gross sales of every spreadsheet in the US. I am told that was the cheap pre-lawsuit price. If you actually made them sue you and they won, they'd demand more. You might be able to afford that 5% for licensing this one patent, but what if you need to license 20 different patents to make the program? Then all the money you take in goes on patents. What if you need to license 21 patents?
