You get no argument from me against the basic value of native browser
support for video and audio, although imo the example you use is an edge
use case and might not work in practice (with my limited knowledge of
modern video encoding techniques I'm inclined to believe that the key
frame nature of video formats will make it very difficult to splice
encoded videos together).
What I question is the practical value of specifying something that
afaics will end up being useless for web deployment (controlled intranet
usage could be possible).

I'm uncomfortable with having a baseline codec. Even if IE would support
a baseline codec, they are likely to also include a codec with a
considerably better quality vs bitrate. Given their market share I fear
that could result in a considerable number of content providers choosing
to use the proprietary format. This would result in a schism in the
availability of web content.
I feel passionately that all public web content, be it text, images,
audio, video or any other form should exclusively be made available
using open, rights free encoding formats and transport protocols.
This would result in lower quality encoding formats given the absence of
commercial incentives to develop such formats and protocols, but the
benefits far outweigh this drawback imo.

Imo for content providers to choose <video> over Flash, client support
needs to be close to Flash. Requiring IE and Safari users to go and
download and install third party software to play content would imo be
considered too much of a hindrance when Flash "simply works".

Frustrated as I am with the current state of affairs, I don't see any
point in taking a principal stance if it will result in being ignored.
