The economy is whatever we define as such. Any inflation favors the debtor and any deflation favors the creditor, but if it's known, is usually factored in the interest rate.
You mean catastrophic deflation is not possible within the bitcoin economy once it has an stable user base?
It hurts entrepreneurs because they don't get financing.
It hurts investors because their investments (so called real capital) don't yield as expected.
The entrepreneurs who couldn't get financing were likely not a good bet. The investors who lost profits because of deflation were betting on inflation. No harm was done to the economy at large in either case, since the last thing an economy needs is more bad investments and failed entreprenuers.
I don't think it is fair to say that all entrepreneurs that don't get financed don't deserve it. With deflation less enterprises are profitable. And some of them that are not financed could have been without deflation.
That's my point, but maybe you disagree.
