Whole whole process of owning debit/credit card associated with your bitcoin stash and ability to use it to buy everything FIAT money can purchase is convenient.
But at the same time it not exactly why bitcoin was created in the first place and I am not a big fan of it and you shouldn't be too.
It is basically not ideal use of your Bitcoin - we shouldn't be doing this - it is harmful for direct adoption of Bitcoin.
Do we really want to be linked to debit cards forever?
