Yeah, I've done the opposite myself - used Windows native webdav integration in file explorer to access my Nextcloud data.
Note that this isn't "syncing" anything in the way that (say) Dropbox would - all the data is stored remotely and you're accessing it online only essentially.
Interesting point. I guess the price of the individual product won't be differentiated based on cost of recycling, but there will still be an incentive for retailers and therefore manufacturers to make products last longer, which might be better in the long run?
