> The point is hollow, as is your restatement of it
No. I'm not sure if you failed to understand the question or you tried to avoid it. My question refers to the core argument involving any economic system: fairness and equity. Why are you trying to avoid touching on the topic?
> You're not. You are not the only person paying tax.
Yes, I am. Everyone is forced to pay taxes, and I am no different. In income redistribution schemes such as UBI you get a chunk of your salary taken straight from your pay check to finance other paychecks. So far this sort of scheme is used to cover salaries representing social safety nets such as pensions, disability, and temporarily for unemployed. UBI radically changes that, as it goes well beyond the role of social safety net and unconditionally extends this to everyone. So now you are faced with a scenario where you have two classes of people: those who sustain the scheme and make it possible, and those who only consume it's resources.
Even if you try to argue there's a net benefit to society, you must face the problem of lack of equity. For instance, how do you justify to people like OP that they should continue working at their jobs so that others can have the privilege of pursuing their personal interests? If you argue that OP is also free to quit his job to pursue his interests then you're advocating for an income redistribution scheme that presssures participants to not contribute to it and instead consume the resources it manages to mobilize.
