Streaming 4K videos (or fitting them onto a 50GB physical disc) requires better video codecs. MPEG2 wouldn't be enough.

Personally, I see the benefit in 4K having a setup to take advantage of it.

Most of MPEG2 was focused on interlaced formats. MPEG1 can already handle 4k by 4k video. MPEG1 and 2 can already handle HD on bluray media. Even at the max bitrate (100Mbps), a bluray can store 1.4Hrs of video.

One could definitely take parts of MPEG1 and MPEG2 to create a new good enough codec for many use cases.

Well people did exactly that - and they named it:

  - MPEG-4 Part 2 (also known under names like DivX, Xvid, ...)
  - MPEG-4 Part 11 (also known as AVC, H.264, ...)
  - VP8
  - VP9
  - AV1
  - MPEG-H Part 2 (also known as HEVC, H.265)
Those are all codecs that build on and extend what MPEG-2 is.
