Some friends of ours never insured their contents for 40+ years, quids in now
They never made a major "claim" then.
I had a £9K burglary claim in 1992, other than that my, and my partners, families have had no reason to make a claim so an avarage premium price of say £100/Annum since 1950's or £6K. Extend that across an average of about 10 properties would have easily covered it with oodles of cash to spare.
It's not really different from any other type of gambling.
Of those who choose to insure, the majority will 'lose' that gamble ('wasting' more money on insurance premiums than they would have suffered in losses/costs in the absence of insurance), but a small minority will be 'winners', possibly 'in a big way' (if they successfully make a claim for considerably more than they have paid in insurance premiums,
Looked at the other way around, of those who choose
not to insure, the majority will 'win' that gamble (suffering less losses/costs than they would have paid in insurance premiums), but a small minority will be 'losers', perhaps catastrophically so (if they suffer a very large loss, far greater than insurance premiums would have cost them).
The problem is that, without crystal balls, no-one knows whether they are going to be in 'the majority' or that ('unlucky') 'small minority' - and, if the latter, nor whether the large loss will happen 'tomorrow' or in 40 years time.
It's therefore down to one's attitude to gambling and to whether one feels one could somehow cope with a situation in which one lost much/all of one's uninsured house contents, particularly if that loss occurred 'soon' (before one had had time to put aside any significant amount into a 'self-insurance kitty'). As Sunray goes on to say ...
However a gas explosion or fire resulting in total loss is a different matter.
... and that's the problem. As above, no-one can know whether they will be one of the unlucky few who suffer a major loss or, if they did, whether it would happen 'tomorrow' or in the distant future.
In passing, I think Sunray's figures are probably misleading. Although the insurance industry is very much 'profit-making', I don't think that it is anything like as 'bad' as his figures suggest. He implies that £60,000 of insurance premiums would be associated with only £9,000 paid out in claims, a mere 15%.
The problem is that his sample of 10 is far too small to show what actually happens 'on average' (over very large numbers of people/households). It would only take an eleventh person who has suffered a loss of £57,000 (far from impossible for total loss of house contents) for his sums to indicate that a total of £66,000 in premiums paid had resulted in £66,000 having been paid out in claims - now 100% ! The truth, averaged over a large number of people/households is obviously somewhere between 15% and 100% !
