I reject completely the idea that either printing money or borrowing money is a viable solution for most economies in the medium or long term. According to you, that must mean I support a Stalinist regime[1]. This is false, to say the least. Other (relative) proponents of a basic income, including such luminaries as Hayek and Milton Friedman, would likely also look at your claim with great skepticism.
A basic income is just the redistributionism practiced by current mixed market economies but implemented much more efficiently (in both the Pareto and administrative senses) than what exists now.
Price levels would be affected by a basic income, but you've got to specify what and how much. Considering supply effects, the likely first order result of a basic income is an increase in the cost of basic goods and also an overall increase in the consumption of them. Goods that are typically bought with, say, the marginal dollar at twice the basic income level will decrease in price but also be consumed less. The market would reallocate capital to more efficiently produce basic goods (defined as the goods that are typically bought with marginal dollars beneath the basic income level).
You might dislike this kind of very limited redistribution. Fair enough, and that is a great debate to have! But you've also got to be thoughtful about the full package. It's not whether you prefer no redistribution to a basic income. It's whether you prefer a basic income to a costly and heavily-administrated redistribution driven by special interest groups.
[1]Also, "Marxist communism"? I'd be curious to ask if you've got even a passing acquaintance with the structure of the Soviet economy. It's fine to criticize a basic income on inflationary grounds, but saying it's communism is so off that it qualifies as not even wrong.
