The place where this does work (somewhat) is with fairgrounds. Buy fairgrounds/gain any action (except peddler). The reason you like doing it this way over using silver is normally Kc, Gm, Expand, etc. If you are going to be buying a lot of fairgrounds (e.g. moderately slow engine needing to mass 6 VP fairgrounds) then you can keep building your engine (particularly if you have multiple hagglers in play). This also allows you to grab actions you currently do not own (e.g. expand, forge, adventurer, Bv) or to pile deplete some key 6 (e.g. Goons, Bv) while piling out the fairgrounds. It is a rare trick, but it can work.
