It depends how it's funded. Strictly speaking that's only the case if it's funded monetarily by a central bank printing more money for a government to fund UBI. For example this is how most countries funded businesses and individuals during the pandemic and what has lead to the inflation you're referring to. Otherwise there is the same amount of money in the economy, it's just been fiscally re-distributed using a UBI policy. You might still see some inflation in some parts of the economy due to rising demand but if people can afford more, rather than less, this inflation no bearing whatsoever on people's actual prosperity. If funded fiscally UBI would outstrip any inflation it might incur and therefore actually represent real-terms deflation for the vast majority of people. As a side note, what we are getting at the moment is the exact opposite: money was printed in huge amounts by central banks during the pandemic which largely ended up in the pockets of people who bought up assets like housing and are now out-competing everyone else in the market and extracting yet more profit. It might feel like inflation to us because food and bills have increased in value faster than our wages, but the wealthy have actually been experiencing real-terms deflation because their stash has been growing faster than their costs.

This is actually the opposite of what studies seem to be suggestion.

The fear is, instead, that it will reduce values, especially housing, and that businesses and wealthier individuals would move away. Admittedly, if it's truly universal, then there would be nowhere for them to move. But the real, often-forgotten underlying gain is that it would create some leverage for employees seeking jobs and raises.

Of course, an "unemployed-only" income would create more employee leverage, possibly matching or exceeding the leverage provided by unions because the employee could afford to strike indefinitely.

You can't just cite an entire field and call it an answer. Especially when than field is basically a pseudoscience.

If you make the maths, the direct inflactionary effects of UBI are quite small unless people were getting tens of thousands of dollars per month, and there are indirect effects pushing in the opposite direction (for example, fewer loans hence less money getting created by banks).

You're making claims that an entire domain supports your conclusion but haven't even gone to the trouble of making the maths to confirm it - you just assumed.

For example the "average household wealth" in the US is $1,059,470 and the average household size is 2.5, so an UBI of $500 per month for every man, woman and child of the United States (rounded to 300 million because I couldn't be arsed to find the exact number) would depreciate that wealth (i.e. inflate its nominal worth) by about 1% per year (assuming 12x UBI payments per year). This is are only the first order effect, as indirect effects push in both directions (for example, it will push salaries at the low end higher, which is inflationary but not by much because it's only lower salaries being affected, and it will reduce number of loans issued which reduces money creation and is thus deflactionary but again the strength of that deflactionary effect depends on actual proportion of loans that are not issued due to UBI making the money available).

All together macroeconomics does not confirm the effect you claim it does (an in fact the Alaskan experiment shows the opposite) but even if you only consider first order effects, it shows an inflactionary effect which is around half of the FED's anual inflation target, so a mild effect and certainly not justifying the statement that UBI "only works in a perfect society where the market doesn’t take advantage of it".
