It’s discrediting valid concerns against card-payments. It’s invalidating how great cash is.
It’s when the worst person you know makes a good point.
And things now are so Culture-Wars-y, nobody makes solid analyses any more, that when the far-right say cards are bad, everybody jumps to thinking cards are good.
You essentially just said “I have money to borrow money against”.
If you had an account with $100k and can borrow up to $70k against it, that isn’t really taking out a loan as it is just borrowing your own money.
Your argument essentially boils down to “just don’t be poor”. The people who need credit and to borrow money are those who don’t have the collateral to spend it otherwise.
You’re just essentially advocating for what rich people like Elon musk do. Take out loans against their stocks so they don’t actually have to liquidate their stocks to get usable cash.
