I agree. And the budget also limits the time you have for thinking about a really good design rather often unfortunately. Choosing the right or sometimes no abstraction is key to making something that is extensible, readable and maintainable. That said, starting out with the simpler concept, usually results in better composability of parts. This is especially true for pure functions vs classes which are not really classes but namespaces artificially made into classes because "OOP". In the end math wins, if you wanna call it like that.
