It turns out that in many of these cases, code is an effective way of doing it, but there may be other options. For a storefront, there are website builders that let you do it very effectively if your needs match one of their templates, there are game engines that require no code, and a lot of accounting can be done in Excel.
What I wanted to say is that maybe you could have done without code, but thanks to LLMs making code a viable option even for beginners, that's what you went for. In fact, vibe coding is barely even coding in the strictest sense of writing something in a programming language, since you are using natural language and code is just an intermediate step that you can see.
The reason programmers use programming languages is not gatekeeping, unlike what many people who want to "eliminate programmers" think. It is that programming languages are very good at what they do, they are precise, unambiguous, concise and expressive. Alternatives like natural languages or graphical tools lack some of these attributes and therefore may not work as well. Like with many advanced tools, there is a learning curve, but once you reach a certain point, like when you intend to make it your job, it is worth it.
