Where `sizeOf(account)` includes size of `account_id`, `account` structure and size of all the data stored under the account.

Account can end up with not enough balance for next two reasons:
- Created new account and didn't give it enough funds.
- Account got slashed.

This account still can receive transfers, hence can be saved.
But to prevent grinding with accounts that don't have balances, we allow for anyone to delete accounts that don't have enough balance. *Note:* this creates possible race conflicts and we recommend all account creating applications to be careful about funding account properly at the creation.

```python
def action_delete_account(account_id, account, ...):
if ctx.signer == account_id or not check_storage_rent(account):
# proceed with deleting
else:
assert DeleteAccountHasEnoughBalance()
```
Account can end up with not enough balance in case it gets slashed. Account will become unusable as all orginating transactions will fail (including deletion).
The only way to recover it in this case is by sending extra funds from a different accounts.
