If they plan to put this things in a low orbit their useful life before reentry is low anyway.

A quick search gave me a lifespan of around 5 years for a starlink satellite.

If you put in orbit a steady stream of new satellites every year maintenance is not an issue, you just stop using worn out or broken ones.

Terrestrial data centers save money and recoup costs by salvaging and recycling components, so what you're saying here is that space-based datacenters are even less competitive than we previously estimated.
