Rollups have a few properties that are distinct from a centralized VISA system. One is that they are cryptographically verifiable, with this data posted onto Ethereum. Another is that they often include permissionless traits - such as L1 smart contract calls that allow users to “force” transactions from L1 to L2 and back even if the centralized sequencer is trying to censor or block the user’s transaction. In this way, you can always withdraw from a rollup L2 back to Ethereum just by signing with your key.
This goes in hand with forkability - lots of rollups are open source - and composability. You can withdraw your L2 tokens back to L1, and put them in another rollup. If VISA or PayPal blocks your account, you are stuck.
