Costs are lower than insurance *AND* you get a more personal interaction with the community.
It doesn't jump out to me as a 'This needs to be a decentralized blockchain based business.'
I think claim validation, fraud prevention and investigation is a pretty professional/specialized discipline and I doubt a decentralized community could do the work for much less/faster/better customer service.
As you stated recently, because there are more trusted, fast, legal exchanges these days, the DEX is having to compete on price.
(Yet the development and running costs for the DEX are higher & customer service is weaker)
BitShares was originally created out of a desire to solve a problem that Bitcoin faced (exchange with fiat) under the presumption that the governments would eventually shutdown the exchanges like they did egold and liberty dollar. With each day that passes it seems less and less likely...
We are put in a situation of competing head-to-head with centralized exchanges which are trusted, fast, and legal.
It seems like the MAS may also be competing head-head with centralized options which are trusted, fast and legal.
Imo a product or service that benefits from privacy, transparency, may be restricted in certain jurisdictions and can be mostly coded are the ones that would benefit from being decentralized businesses. (So crypto-currency, smart-coins, largely code-able private financial products and services, gambling, dark markets, data sharing etc.)
