Case limitations

Is there a reason there is not a single case that includes a camera lense cover, magsafe compatibility, and SEALED dust port covers (rubber flaps or something)???

I work in construction and concrete dust will absolutely ruin my phone if I don't have dust port covers. I would however like the convenience of a magsafe case and the peace of mind that comes with the camera lense covers. But after hours of searching, agonizing conversations with every Ai model, and countless pages on Amazon, I cannot for the life of me find a single case that matches those criteria.

Like do I need to invent one? Literally not a single company is offering them.
