> This argument is a bit scattered. "Rent seeking" is being misused here. It's being used in a more literal-meanings-of-the-words sense ("pursuing monopoly rents") rather than the narrow economic term-of-art sense of "pursuing monopoly rents through influence over public policy by means that do not create, or which inhibit the creation of, additional wealth" (the definition you seem to be complaining about it not adh…
No, a moat is a competitive advantage/ OpenAI in particular is predicated on the belief that they will have a compeitive advantage. ASML is a compeitive advantage with EUV (for now). You can overcharge for if you have a compeititve advantage but that's not the same as rent-seeking. Rent-seeking is fundamentally intermediation like a health insurer putting themselves between a patient and a healthcare provider or priv…
No, a moat is a barrier to people closing the gap of an existing competitive advantage. The barrier is literally the point of the metaphor. If there is no barrier, there is no moat, just a transitory advantage; that's the whole basis of the famous "we have no moat and neither does OpenAI" memo at Google; its not that the big established players had (at that time, or now) no current competitive advantage over open source competition, its that there was no structual barrier preserving it.
> Rent-seeking is fundamentally intermediation
No, rent-seeking is using influence over public policy as a means to extracting monopoly rents. State policy favoring intermediation is one manner of rent seeking, yes.
> Rent-seeking would be Microsoft lobbying lawmakers to require schools and governments to purchase Windows, for example.
That is an example, but lobbying for specific mandates for purchases from the specific firm is a fairly extreme case of rent-seeking, not the general case; a more common for of rent-seeking is firms in a narrow group of leading incumbents lobbying for various standards (either for public market access or government contracts) to be set for the industry that are not a particular burden for existing large firms to meet but which create additional friction for new competitors. In the specific case of software, this can include lobbying for rules that specifically treat open source solutions as suspect and dangerous, as well.
