Rate changes are always a big deal, the trouble is nobody thought rate suppression was a big deal. Trillions of artificially elevated values have already been lost now that the suppression is less, however there is more to come. A house price can mostly be ignored unless you have to sell/buy. All individuals can do is to ensure they can meet their contractual agreements. That's why there has been so much asset selling at deflated prices, because debt that was artificially enabled by suppressed rates is no longer sustainable. Residential property can only go where everything else has already gone and is heading. The issue was never the inevitable slump/crash but the artificially induced bubble.
It's pointless pretending that someone else has gained from this eg "older owners" or "the rich" because as far as asset values go they're probably lost more than newer owners will. If you live in your home or swap it upwards or downwards and port your mortgage including negative equity that is one of several options to owners.
The Government is not "inflating" the economy. They would be if they doled out mortgage relief, which would result in even higher interest rate action, so why add to the flames? While the BoE did too little and too late to curb inflation, it is now doing what it must. Still the real interest rate remains negative, and when inflation is under controlled it would be folly not to normalise at about 4% over inflation. 6% as a nominal rate when inflation is 2% allows capital markets to work. Otherwise money will flow elsewhere where returns are better.
