Transaction is instantaneous, confirmation takes more time.
Confirmation for credit card transactions take up to 180 days, yet, I don't see you complaining about it and im sure you use credit cards a lot. So learn what transaction, confirmation, node decentralization etc means before crying about small blocks.
Very rightly said, people don't complaint about credit cards, but they do complaint about bitcoin transactions, but the fact is they ignore the advantages of bitcoin and focuses only on one minus point.
