Biological immortality does not mean immunity from accidents or homicide. Hugh Hixon, at the Alcor Life Extension Foundation, calculated the half-life of a biologically immortal population at 1 654 years [1].
If we lowered fatality odds to 1 in 100 000 per year (no accidents, Sweden's homicide rate) this figure inflates to 69 315. It's an interesting illustration of how the effects of randomness will not be muted, just shifted.
But the key question is how long do we have to live before we're going to bed at night and backing up all our memories for the day to the cloud. So if we get hit by a bus we just wake up in a few weeks in a rapidly grown body?
I know people will say it won't happen, but are you going to let a 650 year old mind die with its cumulative knowledge and wisdom? Nope, you'd get them a new goddamn body.
