I struggle to see it as a "tweak", since it would fairly dramatically change outcomes and choices for quite a large group, depending on the level it was set at. Something like the post tax income per centile shift I sketched below is a massive change.

You really think it is not different to what we are doing already? Wow, I guess you have never interacted with the welfare system, or know anyone who has.

And completely unobjectionable also? However, as I pointed out, it is practically entirely different from any welfare system that has ever been actually implemented. Therefore fairly remarkable.

Either it is unremarkable and unobjectionable, or it is remarkable and open to criticism. Which is it?

The strawman is I have never heard anybody suggest that a UBI would be unfunded, or would be entirely funded by public borrowing. So it's a strawman. You are pretending that UBI advocates propose something they don't propose, which is pretty much the definition of a strawman.

Sure. I expect everyone would notice. They would have to be pretty stupid not to. But the primary criticisms of UBI are about equity, fairness, and incentives, not making strawman claims about inflationary impacts. I am not a huge fan of UBI myself, but I am a fan of making sensible criticisms.

But it isn't identical to any benefit system currently in use, because we don't have large universal benefits that don't have significant barriers to receive them. The other major objective is to change how certain choices are made by poor people, rather than to create lots of new money.

It is done to different people. Means testing is a burden and a hoop to get through on the poorest. Tax assessment (provided you have a moderately rational tax system) is a trivial load on almost everybody, and only a burden on quite affluent people.

Well, the 3rd post mentions the point, it just doesn't recognise that it undermines your inflationary claim almost entirely.

The difference is that it isn't means tested. Taxes are assessed, which is very different from means testing a benefit. That's the point.

Obviously not, since you take the UBI from higher earners in tax, so that is deflationary by the same amount. You seem to have missed the point entirely.

Because the dollar represents other currencies as well. Supplies from China are more expensive. Here's the Ruble against the Yuan.
