What will you do if a friend who does care and does not want the privacy intrusion comes over to visit? Do you at least give people the courtesy to inform them and ask their permission to have recordings of their voice sent to a third party service?
If enough of these devices are installed, having every utterance recorded will become a fact of life. You might not care, but when people believe they are being recorded they become less willing to challenge authority. That might be something society is willing to accept, but according to your individualistic view, society will not be asked -- it would only take a minority of people installing these devices to create a world of widespread surveillance, and the majority of people would never have been asked for their consent.

If a friend has really idiosyncratic and unusual preferences, they should be good enough to announce those when they visit. Of course a normal host would be willing to unplug their Google Home or Amazon Echo.
