Because neoclassical monetarism says that the only thing the central bank should or could worry about is inflation, that inflation is due to the growth of the money supply, and that the size of the money supply is controlled by setting the interest rate.

Economics is politics by other means

Otherwise it's just a government failing to apply sufficient countercyclical fiscal policy when the catch-up period ends, and the private sector has to take some time to figure out what to do with all the people it previously employed to work in the catch-up.

The affordability of mortgages has been damaged more by people losing jobs and large parts of their income rather than the relatively minor interest rate increases to date.

If people are not being bankrupted by rising interest rates, then how would higher interest rates in the past have prevented them from going bankrupt today?

If interest rates are as irrelevant as you claim, why is it virtually the only policy tool the ECB actually uses on an ongoing basis?

Because the ECB believes that money supply drives inflation. (In the real world, it's the other way around.)
