That is because they are read only and can't be changed. Physical connections don't just fade away, although they can be burnt out if they are extremely abused.
Eprom & flash rely on residual charges being held that leak over time. Once the charge crosses the sense threshold then you get bit rot. Recovering the data at that point starts getting expensive/impossible.
Pressed CD's and laser discs made with poor quality materials also rot due to oxidisation. Low quality materials, cheap large scale manufacturing and short sighted greed made archival of those more important.
