Let me play Devil's advocate for a minute.
If R1 dies and both R2 and R3 have their priorities set to 0, then who
becomes the DR for the LAN segment that all non-DRs can form an adjacency
with? It should be no-one. In that case, R2 and R3 will not form an
adjacency and no routing will occur between them.
