None of the topics you mentioned require hierarchy.
Benefits: "This is an offer I received from corp X for pension funds. Yay or Nay?"
Vacations: Take as much vacation as you feel like. If you take too much, your peers will fire you.
Sabbaticals: If you are worth it you are always welcome back.
Training: Ms Alice. Meet your mentor Bob. Bob will take care of your first steps within the company and teach you the way we do stuff around here. From here on you will have a variety of mentors for the different areas of work you will be working on. You will receive a full voice within the quorum after period X and after your peers have been satisfied with your indoctrination to the way we do shit around here.
Accounting: I don't know why orders and invoices could not be handled in the way I prescribed. There would still be an "accounting" function. Processing incoming and outgoing payments. You can't have Jack the lorry driver signing the financial reports, can you?
Neither do they require pizza. They are just functions which must be performed within a company, and their existence doesn't require that the people in charge of them have authority over, say, the programmers. I mean, the sales folk don't boss you around, nor you the accountant, right?

There's a bit more paperwork involved in that than just that where you live, I'm sure. There should probably be someone who knows it, and files the business-end of it. Hell, with their knowledge, they could even offer you advise about the different conditions and regulations as you are seeking pension funds and insurance!
Also, individual employees may have had agreed different terms and conditions in their work contracts that someone should deal with and keep track of them.

You'll meet him at the meeting room as he arrives from Big Training Corp, Inc. We took care of the cookies and the billing, don't worry.
Also, who calls the plumber when the sink gets clogged and pays him? Oh, and somebody needs to find a new cleaner when Joe retires next month (you knew that Joe retired next month, right?)

It sounds rather hard and it's probably just something that should be handled by a few qualified people anyway as you say?
HR has a lot of laws they have to follow and paperwork to do. While you could put these functions under legal, most companies have HR separated because of the amount of work that can be done by less legally trained individuals.
