> Almost no voter has the expertise to accurately allocate resources in a country.

That's true as far as it goes. However if we had the ability to individually vote on allocations, presumably most people would delegate the details to an expert of their choosing, while taking a stance on high-level classes of expenditures, for example "I will vote for the <insert expert> budget because it reduces military spending and increases healthcare spending", or whatever your policy preference is. Basically Liquid Democracy[1] of some sort (whether the partial delegation is built into the system or implemented outside the allocation voting system).

I do agree with your general point that direct democracy can be problematic, particularly when a binary choice is presented rather than a continuum of options. E.g. see the CA ballot measure system which often results in "choose A&C or B&D"-type choices which exclude certain preferences from being expressed. I think a more granular direct democracy might enable better decision frameworks though, specifically by enabling more options for delegation.
