Agreed that you can't run a country on tax-via-inflation. But it's worth noting that the bank of england monetized government debt last month and the markets didn't bat an eyelid.
That is kind of an oversimplification. The UK government arm twisted companies into not doing mass layoffs using tax policy and some legal wrangling. The amount of debt monetized was small relative to what the US is doing. While the US dollar has the advantage of being the global reserve currency the pound sterling gets substantial value from being relatively well managed. And markets did tremble significantly and there is much speculation that the rally in London and New York exchanges is actually rather shallow and flimsy.
