I’ve found this to be one of the strongest arguments for a strong social safety net, at least one centered around helping people to find new jobs or be retrained for new careers. Taxpayers and the economy in general do not benefit from preserving unnecessary jobs (whether in the govt or the private sector). It would be much better if society accepted that job & career turnover are necessary to a healthy functioning economy and embraced that reality by countering the disruptive downsides.
Even free market economists like Milton Friedman have argued for such programs. And at least for the time being, there is still plenty of work for people to do even if it’s different than what they were doing previously.
The hard part of this is designing the system in a way that avoids inevitable abuse, and then convincing people that it does so effectively.
