3. Get hired online or offline and receive your salary in bitcoin: should be self-explanatory.
You are starving to death? Find a food and eat it.
You are homeless? Go buy a hause
You need money? GO FIND A JOB

Pritty much nothing new in here.
It's not the same though. You'd be surprised how many people think that the only way to acquire bitcoin is by buying it with fiat. They need to be reminded that they can also get paid in bitcoin, whether their full salary for a new job they get hired for or for their old job and part of their salary in bitcoin.
Those who are self-employed could also add the option to receive the payment in bitcoin (like a merchant selling goods for bitcoin to whoever that asked for it).
