Of course, were you living in certain areas of Spain or Ireland (where some properties have lost up to 75% of their value) then you would have been asking why anyone would ever choose to take on the huge risk of ownership.....
And there, in a nutshell, is your answer. In a politically stable environment, with stable supply/demand there is virtually no financial difference between buying and renting. Renting will be cheaper than a repayment mortgage but if you put the difference into a savings account earning libor, then after 25 years the cash saved up would be enough to buy the same property outright as you would have brought on a mtgge 25 years previously.
Thing is, we have politics, inflation and unbalanced supply/demand which buggers up the whole landscape, meaning that whichever side of the buy/rent market you sit on, you are taking a very serious gamble, with very serious money. And should you think "house prices have beaten inflation and other types of investment because of demand, so are a safer bet" or "house prices have beaten inflation and other investments, so must be due a huge downward correction and are therefore a very risky bet"? Which one is it to be? No one can answer that. Demand of course would collapse if we left the EU and all the immigrants were asked to leave not sure the daily mail will be taking that stance any time soon - just as has happened in Spain with the whole 'second home' community fleeing for the hills.
Many other countries think the British are barking mad for our obsession with ownership, by the way.
