Equal in the sense that a byte of a simple transaction and a byte of other types of transactions are not discriminated.

(…) a reason that the witness data is fundamentally less expensive to the network than the state transition data (inputs + outputs). If you want to contest that claim, I’m open to hearing it.
Yes, I do contest that claim. I haven’t found evidence that would support it. To the contrary, the network sees 1 byte as 1 byte (indiscriminately) and the deviation (so-called “witness discount”) is being exploited apparently (to the detriment of simple transactions, decentralization and value of sats).
