Yes that is one small dimension of why the dollar is valuable. But a far bigger part is the fact that using dollars enters you into the US financial (and by extension legal) systems which has been far more stable, reliable and predictable than other systems over the last century.

The Swiss central bank has even deviated from their usual stable policy since 2008 and yet still they see inflows.
