The reason for this is the following：

1. First of all, the reason why Alipay restricts collection is generally because the account involves transaction violations. For example, transactions involving gray property or large amounts of unknown origin will trigger Alipay's risk control, resulting in limited collection.

2. Secondly, Alipay is a real-name registration system, and it will still be your name after cancellation. Only your credit difference will be restricted from collecting money, and your name has been on the credit, so it will be restricted from collecting money.

3. Thirdly, in the case that Alipay's function is limited due to violation of regulations, it is impossible to cancel the account and re-register. Even if you can cancel your account, you have to wait 90 days, and it may affect the use of other functions.
