Would the Insurance companies withdraw from offering such insurance in the future?
The short answer is, yes, probably some of them will do so. However, keep in mind a couple of other factors.
One, insurance rates are based on actuarial calculations to forecast the likelihood of claims made and level of payment. However, there is insufficient data today to make reasonably accurate actuarial predictions suitable for setting such rates. Bruce Schneier has commented on this problem more than once:
Two, sadly the insurance industry has had its share of companies whose profit model is based on a claims management policy of, "deny, deny, deny appeal, defend denial in court, pay only when under a court order." I seem to recall courtroom movies based on the antics of such companies.
