Because now, sending coins into P2WPKH is cheaper than sending them to P2TR, even though finally, when those coins are spent, the blockspace usage is cheaper for Taproot (when you spend by key) than for Segwit, because public key hash is not stored anywhere. But of course, because the cost is splitted between sender and spender, it is more profitable to send to P2WPKH, and spend from P2TR.

The difference between P2WPKH and P2TR is a different topic, I think.
A single bloated transaction would be treated with higher priority
than a number of simple transactions of the same total size and fee -
irrespectively of P2WPKH and P2TR type.
