Faced with decision overload, most people get more productive where most of the decisions are made for them by somebody else.

If you had to consciously make every single decision about everything you do you would die. That's where habits and patterns come to reduce the number of decisions you have to make to a reasonable level.

Most software development projects really are the same as a lot of other projects. You get API services that basically shuttle data between database and web interface, you get frontends which basically shuttle data between APIs and UI, etc. There is no need to invent everything for every project you do, it is much more productive to just focus on things that are specific to your project and adopt the rest from either your experience or some ready made guidebook.

It is not necessarily a lack of trust. It is just that when I hear some development manager to start on a journey of reinventing everything for a pretty mundane backend project it immediately suggests to me a lack of common sense or prioritising personal goals over good of the project.
