Everone should consider state actors as a threat because they are. They maybe are not specifically after you. But every now and then some big box gets popped leaking all kinds of personal information (including yours) and the actors are probably state sponsored. Also it is not state actors scanning your data, many cloud providers do so.
If you have a state actor as threat model you probably want to remove iCloud backups (see link):

In the first half of last year, the period covered by Apple’s most recent semiannual transparency report on requests for data it receives from government agencies, U.S. authorities armed with regular court papers asked for and obtained full device backups or other iCloud content in 1,568 cases, covering about 6,000 accounts."
