I'm sure most people would have fun if someone financed their vacation. The difference between your situation and basic income is that your income is because you are providing enough value to people that they pay you money, while basic income is other people paying you money (taxpayers) with no expectation of providing any value.

"I really enjoyed my vacation paid for by my automated business and therefore basic income will improve people's well-being" is not a good argument for UBI. Of course people will have a good time when someone else is paying for them. But how does society afford to do that?
