[Star Wars prequels] so who came up with the battle droid idea anyway? Is there a galactic equivalent to sams club out there that they bought these things from in bulk? Like seriously man, those things are the cheapest things to put on the battlefield, one could easily just move them with the force.

And they have no apparent durability or strength. Sure they’re loyal to the cause but really? Who gave this idea the green light?

They were being deployed by the Trade Federation, which is just a shipping and trade conglomerate rather than a planet or nation. So they didn't have an actual loyal army of soldiers and used their money to buy the droids instead.
