I don't like fiat, but this is a good point.
What would you prefer to do?
1) Take a $20000 loan at 5% interest rate and repay it 10 years later.
2) Take a 1 BTC loan at 5% interest rate and repay it 10 years later.
I think acquiring 1 BTC in 2032 will be darn near impossible, unless you're super rich.
On the other hand, 20k USD might not even be enough to buy a car due to inflation... easy repayment!
So yeah, I don't think BTC incentivizes a debt-based system.
This is both a good and a bad thing, depending on how you see it... some people consider debt a form of slavery (with invisible and not metallic chains), while others consider a debt-based system necessary to promote economic growth.
But economic growth (due to QE) also means that bubbles will be created from time to time... even BTC's bubbles every 4 years, since we're still in the fiat standard.
