> If the work your going to be doing is useful, then why don't you do it?

For me: I am doing/learning how to do it, but I don't have capability to monetize it right now.

In general: I have personally known many people who want to have a career in X, but can't because they are working three jobs to try to house and feed themselves.

> [I]s it objectively not as useful as your current occupation?

For me: It is objectively more useful then my current occupation. I can't explain more without revealing more of my private life than I am comfortable doing here.

In general: Regardless, something being less useful then something else doesn't make it not useful. 75% is less than 100%, but is still greater than 0%.

Also, bonus argument for UBI.

Most (all?) propositions for UBI I have seen will cover only the bare minimum. Almost everyone wants more than this, and will be willing to work to get the extra money.
