there's a slight difference between one, a couple, a few, several and "lots". It's one of the first things you learn in English.

If I ran out of money it shouldn't be okay for me to rob someone's else money. The same way if I can't afford a house house I shouldn't squat a house.

If one can't afford a house, he or she should: - complain about the government house development policies - search for social housing if available - get a better job - not squat someone's else house - not have children and use them to justify squatting, which is very common - etc
