The thing I dislike about it most is that it enables more funds to be lost from a one week powerdown by a hacker.

How about 130 weeks instead of 13? 1300?

1. There are hundreds of tokens with no staking.
2. Make a alt account you dont use, put all your funds in it and delegate to your main account.

This is a major non-concern that relies on making the case that people are dumb and cant manage their funds so their Steem must be locked for longer.

I agree with aggroed as far as the investment issue goes: if someone just wants to speculate in the coin, they can just avoid powering up.

Thats painfully stupid and shortsighted. You want your community to participate more in trading. Those that believe most in STEEM are the ones that will create upward pressure on the price since they are more likely to buy in. Having only speculators, which we do now, that only simply follow BTC price movement is what is screwing us.

In summary, I don't see any likely value-add from this change, and I think Steem holders who get hacked will lose more money as a result of this change.

Fear-mongering over a very unlikely occurrence makes for a very poor argument.
