What would you do if this happened tomorrow? Would you continue working or quit your job? Why?
That's a funny question, since I did actually quit my job four years ago.
Once I gathered enough money so I would not need to work in the next ten years, I just stopped working.
So I can actually answer your question without any "if".
In a sense, I'm a living proof that this basic income is not a good idea.
You should not underestimate people's laziness.
