Richard Murphy (https://www.taxresearch.org.uk/Blog/) argues that the government doesn't need the gilts market - indeed that it is the gilts market that needs the government - though he says little about the currency speculators.
He also argues that the 'national debt' is a misnomer - it's really a useful national savings scheme that should be expanded (and in any case it's mostly owed to the Bank of England, ie. to ourselves, so a very odd kind of 'debt' indeed).
As things stand, 'unfunded' public expenditure might crash sterling, just as 'unfunded' tax cuts did, leading to higher interest rates and recession (though not, I think, as bad as the Truss crash, because there is no evidence that tax cuts create future growth, but much public expenditure certainly does).
So there has to be a comprehensive reform package: ending BofE independence, weakening the value of sterling - interest rates - inflation links, ditching the current 'fiscal rules', and as Elaine and @Sine_Nomine say, using tax to curtail inflationary pressure.
The odd thing is that Reeves has spoken about making tax 'fair' - all it would actually take, I think, is a few steps to equalise the proportion of income and wealth taken in tax at all income/wealth levels - such as equalising tax on earned and unearned income - because at present the tax system is so scewed in favour of the rich.
This could be phased over a long period - because governments don't need to remove excess money (inflationary pressure) until perhaps long after they've spent it into the economy.
Sorry to go on - just thinking aloud here really...
