I agree with this. Homogenization allows the ATP to promote tennis as a consistent narrative and hype this 'Big 4' to ridiculous extents.
The detrimental effects are far bigger though: we have one dimensional top players who throw tantrums as soon as the condtions change even a bit and talented players whose tennis style is not baseline grinding can never really fulfill their potential. The only 'advantage' is more money for the ATP and titles for those whose style suits the current conditions. All the rest are nefarious effects
The way it is now, every condition has been virtually controlled apart from the sun and the wind at outdoor events. They are trying to do this well but since they make so much money financially with the marketing that this is so great, when the surfaces are virtually the same. It's 101 Marketing and Spin "accentuate the positives and hide the negatives". Since they can virtually guarantee the top 4 at these events make better sense.
Nadal playing on one of those ice rinks would be funny, but if he was good enough then he'd win there as well.
