Once you have a large enough following for some reason (and ideally a fairly committed one; IDK if "follows someone on YouTube, like MrBeast" is enough -- has to be more like "my favorite musician/artist" or "business idol" or something), the rest is comparatively easy. You could pay people for all the stuff.
Basically the five routes today are: 1) Network State (stuff less than a state at start, ground up) 2) Negotiating with an existing state (free trade zone with more autonomy) 3) Seasteading (mostly an engineering and capital problem) 4) Space (also an engineering and capital problem) 5) Military conquest. Over the past ~70 years the last option didn't really exist, but increasingly it probably could work in some very specific locations, especially if you can find a fig leaf of "this local guy actually needs to be in power, not the guy in power now".
