I agree with that regarding modular synthesis itself…
On the other hand I can totally see the appeal of building a personalized groovebox/setup with “macro modules”, full synth and drum voices, a nice sequencer and some fx.
You can choose the synth and drum voices that totally appeal to you - in regular grooveboxes, I usually always find something that isn’t quite right.
Also, there is the potential to pack everything you need for making tracks in one single case, that only needs one power source, instead of cluttering all your desk with single drummachines and desktop synths etc…
Of course I know many clutter all their room with dozens of modular cases… But that’s another story
