>If you think that is honest behavior, then bury all your money for 10 years and then try to spend it. Suprise! You've been robbed.

That does induce people to spend,invest or save(savings in banks are loaned out to others by the banks) which drives the economy.

The problem with bitcoin right now is that it's being thought of an investment to hold on to, instead of a currency that must be exchanged for goods.

Imagine if the dollar was appreciating in value big time every week and month. People would stop spending and just hog them. The economy as we know if might collapse and lead to a full blown depression.
