I am young, but not so young as that. I do have a credit card, I just don't use it for anything except the monthly cost of server hosting (to keep it in use). Despite its disuse, I have an "exceptional" credit rating, probably mostly due to the age of the account. So I appreciate the point about credit history, but my habit of preferentially using debit doesn't seem to have been to my detriment on that front.

As to fraud protection, I agree, but as noted in another reply, I wish I understood why the protections afforded to credit don't also apply to debit. There must be some systemic reason for it that I'm unaware of. As it stands, my best guess is simply that "it's a perk to entice people to use credit".

The reason is just that it would be more risky, I think. Compare the scenarios:

1. Scammer clones your credit card with a skimmer and pays for $500 of clothes at the mall. You dispute the charges. The funds are actually not given to the store for a bit given that credit transactions take a while to settle. Upon the dispute, the store now needs to prove that you were there and bought those clothes to get their $500, or else the bank/Visa won't pay them.

2. Scammer clones your debit card with a skimmer and pays for $500 of clothes at the mall. You dispute the charges. The store already got paid though. The bank doesn't want to give you another $500 in case you are actually in on the scam, then they'll be out an additional $500. Eventually assuming they can't prove you actually bought the clothes, I think the store would have the $500 confiscated, but usually you're still liable for $50 if you reported it quickly enough, but could be more if you take too long to report the fraud.

Of course debit cards can easily be converted to even easier-to-launder money substitutes, too.
