Empirical data suggests that one does not need forced sales for house prices to go down or vice versa. Look at any advanced economy such as :
Australia: Has already had >10% YoY decline thus far and the economy is expected to clock >3% GDP growth. Just today IMF came out with a warning of a 'sizeable bust'
^www.theguardian.com/australia-news/2022/dec/27/imf-sees-potential-for-imminent-sizeable-bust-in-australias-housing-market^
US: Just reported third monthly decline in prices and the economy still has red hot labor market with solid wage growth over the year.

One could go on about about countries such as Sweden, Canada, New Zealand etc , all of which have had c10% or more price declines with their respective economies not in recession yet.
Therefore, while it is nobody's case that there will be masses of people in negative equity soon in the UK, there is no reason to believe that UK will remain untouched from price declines (BTW prices have already declined >3% since August 2022). And of all OECD countries, UK has the worst economic forecast and has had slowest rate of rate increases.
Froth has definitely come off or will come off soon from the market. The days when sellers would just add 50k-100k to the price has gone. Most people will do fine. Just the people with 5-10% deposit and those that bought recently may suffer.
