I would have said exactly the opposite: blurred strokes belong to bitmaps, you are still thinking that pixels are square over a regular area that can opnly be rotated by multiples of 90 degrees.

SVG graphics are clean, result in NO blur at all. They don't even need any Truetype-style hinting. You've probably looked only at early non-conforming implementations using bad approximations. But precise rendering algorithms for SVG are specified and fully tested (this is not the case for bitmaps whose support is much more problementic: see what happens to photos and videos when editing them! Never twice the same result, and lot of losses and artefacts everywhere, including bad undesired effects, and notably the moiré effects which are much worse and do not reproduce what natural scaling would do in your eyes, that are not fitted to a perfect rectangular grid).

So no, it's perfectly possible to create a vector image that results in unblurred strokes at arbitrary pixel sizes. What you want is a geometric transform to exhibit more some details: it is in fact impossible to do that with bitmaps except by sending variants tuned for multiple resolutions: you do that for a limited number of resolution and assume it is enough, but this is not the case, so you add more, and finally you have enormous images that are widely redundant with each other, and better represented by converting their 2D model to 3D and an adaptive 3D-to2D projection. you'll do that easily with vector graphics, not with bitmaps (or their extensions called "mipmaps" which are only approximations not really scalable because they're still all based on discretely sampled planes).
