Why I Like 2♣ Part I -- Uncontested Auctions
The one glaring point that I would make is that one would not normally cater calls to a 4♦...5♦ interference. Sure, it is possible, and it is a concern. However, an uncontested auction is also quite possible.
For me, at least, the uncontested auction is greatly enhanced if Responder bids 2♣. An extremely likely occurrence, when Responder has a void in diamonds, is that Opener will, in fact, be able to bid 2♦, or at least 2♥. Either will allow me, at least in my methods, to now bid 2♠.
The 2♣ call by me will enable partner to cue slow club honors. As I lack any spade top honors, I'll expect partner to be able to bypass 2NT (a denial cue in my methods -- would deny KQ+ in spade honors) to cue 3♣ with the club Queen or King. If Opener bid 2♦ at rebid, I'd now cue 3♥. Partner might cue 3♠ when relevant grand considerations are there (all three top spades), and I'd cue 3NT.
At this point, if partner held KQ in clubs, he'd cue 4♣, and I'd know what was up -- a lay-down grand. If not, I could still check on the club suit (King or Queen) when he bids anything, as 5♣ (a suit I bid) asks keycard, but with the keys being the King and Queen of clubs (spades already being known).
Back up. If partner lacks any club cards, he'd bypass 3♣ to do something. Later, then, he could cue club to show the stiff. That's OK also. Maybe his alternative cues tell me something as well. Or, he bypasses 4♣ to deny a stiff. Whatever.
The point, initially, is that a 2♣ call starts tremendous auctions when the auction is uncontested. 2NT is a mess as an alternative.
Part II -- Increased Likelihood of Contested Auction
A somewhat minor point, perhaps. People overcall 1M-P-2NT on air, as they should. It is the achille's ankle of Jacoby 2NT that parallels the Precision 1♣ interference. I've seen KJxx and out. The known nine-fit induces interference, and higher interference at that. In contrast, 2♣ accomplishes much less, and lower, preemption. Exchange of info is easier. Thus, one "protection" for this is when 2NT shows primes and relatively balanced, because then we can HIT the interference. 5440-based 2NT's mean interefence without ptotection.
Part III -- Quick Snapshot
The third reason for me is the prep for the interference. If we do get a diamond preempt, Opener/Partner might do something, like support clubs, that could be useful. Partner might introduce hearts. His focus will be different and, I believe, more helpful. He often will be able to act at a lower level (2NT-4♦ looks like 2♣-3♦, IMO).
If partner cannot act, possibly in the same sequence, I have some more info anyway. In any event, worst case scenario, I still believe that partner is better placed as to evaluation of his slow club honors. If I have to pick a preferred start, I'd rather have 1♠-P-2♣-4♦-P-5♦-? than 1♠-P-2NT-4♦-P-5♦-?
Conclusion
The final point is that 2NT cannot handle the world's problems. It is a very preemptive method of supporting a major, taking up a lot of space for us. If the bid can be any wild combination of patterns, then the inferences available from failing to bid 2NT are too difficult to untangle. Structural integrity, for me, includes one key concept. Quantitative and shape bash calls are done with primed hands; slower auctions are used for mixed-honor and mixed-shape hands.
