This seems incredibly shortsighted. If you're building an application by yourself you're gonna remember the relations and dependencies - but even on a small team (say ~4 devs) or even if you don't pick it up after a while, there is going to be stuff you forget.

It's also nice when you move stuff around, you can rely on the LSP to rename and fix everything that breaks. If you have a simple website it's fine, but when you start to have multiple components... Losing typing is a huge deal.
