A government can print money, however the very value of it will decrease because there will be more money for the same amount of products to buy, and inflation will quickly offset the effect of this newly printed money. Moreover many citizens, especially those who have savings, hate inflation and will fight against such a trend. Taxes and various other "resource extraction" also are limited because more and more citizens will fight against such measures, up to deliberately reducing their income or living the country.

A business can in a way "print money" and "extract resources" by raising its prices. In many trades their customers will remain customers because switching would be more expensive. But there is also an obvious limit there: the amount of prospects will decline and at a given point more and more customers will depart.
