No, you don’t understand how insurance works; reserves are built up over time from policy contributions. Some of those are paid out in claims, and some used to acquire re-insurance to hedge the insurer’s risk .. but NONE of the policy contributions should ever be paid as dividends

If you’re curious, have a read on how Lloyds of London started, and in the absence of any other insurer, how they hedged their long tail risk

Insurance will work well in a bitcoin denominated world, premiums will reduce and the need for insurers to “actively manage” their reserves will significantly reduce
