True, but if you have digital display - that is, which have separate, immovable pixels, working with pixels and not with vector-based analog primitives - you'll eventually have to convert "vector" picture into "pixel" picture.

Do you have a vector display of some kind?

No?

So someone somewhere is going to need to rasterise your vectors if you want to see them on a screen, aren't they?

I wish for that world to exist, but rasterized images are much easier to share and render nicely in iMessages etc.

One reason is to generate screenshots of HTML by combining this technique with SVG <foreignObject>.
