As long as the weekly compounding rate is greater than zero, then powering down will not result is a zero balance at the end of the two year powering down period.
Is this a problem? I do not think the 4.3% weekly rate of return will last forever. I fully expect the weekly rate of return to be less one day. At this stage of SteemIt the inflation rate makes sense, but it will likely change over time. Time will tell.

It may well change in time. I'm not sure if it matters that you cannot take it out as long as you can see some return on your investment (time and/or money)
Cheers for sending me a 'bonus' :)
