Of course! Why did no one realise this! When horcruxes are basically copying yourelf like an upload (cf. the work of Robin Hanson) then all of the standard theories apply; when you have many tasks to do, run copies of yourself to do them. What other Hansonian techniques could the horcruxes be used for?

I mean, Tom Riddle should be having an excellent life, whilst he's made a copy of himself to figure out how to run the world. Then that copy could be responsible setting up the above plan, and made two more copies.

This reminds me how it's said that Quirrell is inspired by Hanson. Not just his cynical explanations of human behaviour, but also his economics of copying minds. Neat.
