Not if you genuinely don't care about impressing anyone. A real programming job involves convincing someone your work is valuable enough to pay for. A welfare scam involves convincing someone you deserve free money. Both are too much social involvement if you prefer a hikikomori lifestyle of writing code nobody will ever use.
Zero users and loving it! is not necessarily hyperbole.
Under a UBI you would not have to fake anything since the only qualification is having a low or no taxable income.
Again, this is how it works in most developed countries under welfare systems without issue. The majority still seek real jobs because they want to live above the base level of income required to live. A UBI won't be paying for your overseas holiday and fancy car.
