This article is kind of stupid. I guess people don't realize that there already is a limit to the amount of cash you can withdraw. The daily limit from the ATM is $300 for me. I don't know what the limit is if you walk up to a teller, but I'm sure there must be one. The bank only holds so much cash.
The article said nothing about restrictions on writing checks, using a debit card, or transferring funds. Anyway, who uses cash any more?
This article is based on the myth that money deposited in an account at a bank is stored as cash in the bank's vault, which of course is completely false.
What account do you have where the daily limit is $300??
