Well if you don’t have an actual use case for it, don’t try to artificially find one.
The only thing I use USB sticks for nowadays is for OS installs.
For everything else their write speeds are slow (even the more expensive USB sticks slow down to a crawl after what feels like not even one complete overwrite) and they are unreliable.
Sure, if you want to carry around random OS installers and live environments, go for it. I personally don’t have a use case for it.
