No, any centralised company offering to store people's bitcoins for them are doing their users a disservice in not educating them correctly in how to use bitcoin safely and securely. Stop letting other companies look after your bitcoin for you, idiots.
They're in business to offer their services like a bank does, just a different market. Nearly all people that work for a living keep their funds in a bank and their retirement in some sort of broker's hands. Face it, it will only be the techies that store their coins in cold storage off the reservation so to speak. In order to get new people feeling safe in this market and shedding us of the bad PR of the past (gox and stuff), it's a must for the likes of coinbase and circle to have the reputations of credit unions in terms of users storing their money, coins or whatever. Agreed, most people keep their gold and silver on hand but this stuff is way different when the average new person is extremely busy w/ work, family, hobbies and whatever else. Just saying.
