Relevant part of YouTube TOS that'll come into effect on 2019-12-10:
YouTube may terminate your access, or your Google account’s access to all or part of the Service if YouTube believes, in its sole discretion, that provision of the Service to you is no longer commercially viable.
However, it's not clear whether "Service" is YouTube or whole Google account. As we've seen in Markiplier affair, violating YouTube TOS meant that people lost access to their whole Google account - including gmail and gdrive.
