Let $X$ be a finite-dimensional normed space, and $V\subset X$ a vector subspace. For a point $x\in X$ we define a closest projection of $x$ onto $V$ to be a minimizer $v^\star$ of $||v-x||$ amongst $v\in V$.
Under what conditions on the norm, can we guarantee that for all $V$ and $x$ there exist a projection $v^\star$ of $x$ onto $V$ for which furthermore there holds $||v^\star||\leq ||x||$?
note based on comments It's obvious that $||v^\star - x||\leq ||x||$, but I didn't ask that. Euclidean norm satisfies the property and max-norm on $\mathbb R^2$ doesn't satisfy it, as fedja points out in a comment. The question is, what norms do/don't satisfy?
Please if you put a downvote, kindly explain why, so that I understand my own errors?
