The real issue is not about ProV's, it's about the fact that these 50 different golf balls all can be hit into the stratosphere by a Touring Pro and Top Amateurs.
All that the multilayer construction did, was to provide a superior combination of spin and distance to elite players, who were in a position of skill to use that combination.
Anyway, there is scarcely a recreational player alive who should fear that a wholesale revision of golf ball regulations (if done correctly) would harm their enjoyment of the game.
You're dead right about the impact of multilayer balls, it allowed thebest players to effectively use a higher percentage of their power on long shots--just a TopFlite would have--due their relatively low spin on long shots. At the sime time, it gave them a useful amount of spin around the green. It's as if they'd been allowed to change balls like the do clubs--based on the length and type of shot they wanted to play.
I believe that if someone built a golf club that did the same thing, EVERYONE would want it banned...
The trick would be create a ball that was like a balata in that the harder you hit it, the more demanding of precision it became. That's precisely what balata balls did--with ultra-high clubhead speeds they spun so much that elite players had to throttle back to keep them in play. This effect still allowed the longest, most accurate players to prevail, but it also meant we could play on WIDER and shorter courses without having too many super-low scores.
My solution to the problem is the same one that the USGA used in the 1930s--a lighter golf ball.
Now, there's already an essay on here explaining why this is a bad idea --
http://golfclubatlas.com/in-my-opinion/john-vander-borght-the-balloon-ball -- but i think John is wrong. With modern balls and clubs, the "horrible" effects of a 1.55-ounce balata ball, hit with 1930s clubs would not be exhibited.
Given my knowledge of shotgun ballistics from another life, there are some easily understood effects of reducing the cross-sectional density of a round projectile. The rate of decelleration is one thing that would change, and that rate is proportional to initial velocity.
So... a ball that weighed 1.55, or maybe 1.58 ounces, would lose its initial veolcity faster, and the effect which would only be most noticeable at the high ball speeds. Choosing the weight would control how this effect worked.
It would curve a little bit more easily than the current ball, bringing back some of the balance between power and ball striking to competitive golf.
It would sit up just a bit better, making it easier for the shortest hitters to get it airborne and it would saty airbrone a little more easily, giving them slightly more carry (which is something 90% of Sr and women players need)
It would make certain kinds of short-game shots easier, but I'm betting that it would make others more difficult.
It could give the manufacturers free reign on innovation in other areas of ball development, and maybe even remove some of the concern over regulating clubs.
Finally, it would create a standard that anyone with a digital scale could test for.
Alas, it's unlikely that anyone is going to go for it, thanks to thinking like that in John's essay.
