It is a diriment impediment because marriage is ordered to marital relations. Complete and permanent and antecedent inability to engage in marital relations means one can not give marital consent. No marriage vows can be exchanged.Let us, then, look at this issue from another perspective. If the Church does not require consummation then why does She teach that impotence is a diriment impediment to marriage. Note first that it is a diriment impediment and secondly that it is a divine natural law impediment. Why would the Church teach that a person who cannot perform the conjugal act cannot marry and then teach that those who can perform the conjugal act may marry but do not have to perform the conjugal act? I think the importance of consummation is also seen in the fact that an unconsummated marriage, even a sacramental one, can be dissolved.
But the fact that marital consent is given and that one is capable of it does not mean that its exercise is mandatory.
(Note that one could not licitly withhold marital relations unless freely consented to by both parties, since by virtue of exchanging marriage vows, each spouse consents to marital relations with the other.)
