Of course they are willing to do so, the more people buy their already overpriced bitcoins and sold them on Bitstamp, the larger the price gap between the two exchanges, the more profit they could make from doing arbitrage between the two. As the only USDs that could leave MtGox now is their own dollars, they have a monopoly on doing this. They could earn 10% profit doing every round of arbitrage. With this rate and without competition, they could double or even triple their money in a few months. Very sound business plan from MtGox!
Doesn't make sense. For this to work people have to keep depositing fiat at MtGox. Otherwise they are limited by whatever fiat customers had on deposit at the time the withdrawal freeze started.
Don't you get it?
Canceled withdrawal is similar to a deposit, it makes available new money to buy their overpriced bitcoins. A canceled withdrawal is usually followed by a buy order, because people are desperate to get their money out of gox.
Also, some people are continuing to deposit money to MtGox despite their incompetence to handle withdrawals. If no one is depositing money to them, there shouldn't be any reports of a deposit delay of more than 10 days.
That shows that some people still have confidence in MtGox. Actually I don't know why anyone would send money there because you can buy coins cheaper everywhere. Perhaps some people are just ignorant.
