Not even for streaming. But for general "safety while on the Internet" when the devices (Mac, iPhone) are mostly on public or not-so-secure WiFi (at the residence or on the go). Plan is to keep it always ON or almost always ON.
Not necessarily for the UK.
(Other than Mullvad)
But a VPN would have been more appropriate for this task and if ever I needed to use a different IP from a different country (that would be rare and mostly to access websites for a short period) I could just do it easily.
