Yes, I’ve actually seen people say that, but cells do use myosin to transport proteins sometimes. That uses a lot of energy, so it’s only used for large things.
Cells have compartments with proteins that do related reactions. Some proteins form complexes that do multiple reaction steps. Existing life already does this to the extent that it makes sense to.
Humans or AI designing a transport/ compartmentalization system can go “how many compartments is optimal”. Evolution doesn’t work like this. It evolves a transport system to transport one specific thing in one specific organism.
It’s like humans invent railways in general. Evolution invents a railway between 2 towns, and if it wants to connect a third town, it needs to invent a railway again from scratch. (Imagine a bunch of very secretive town councils)
