Dan, have you thought about the effect of applying Steem rules to insurance? Each reward motivates the actions being rewarded. If you reward writing interesting posts, more posts will be written (both good and bad ones). If you apply the same rules on insurance claims, there will be also more of them.

I understand the economy behind it that with bigger number of posts / insurance claims the reward is split among bigger number of authors, so the individual payouts decrease. But some people perceive it as a lottery or just don't behave purely rationally, so the motivation is still increased.

Another thing is that you can't expect the same participation in reading Steem posts as in reading insurance claims. Who would be willing to read through all the misery that will be posted there? And if people won't read the claims, then they won't vote or their votes will not be well informed.
