I am not advocating for anyone linking existing npubs to a Google account. Current Nostr users don’t need to change anything at all. This is all about making onboarding easier for everyone else who either tried Nostr and gave up or never joined in the first place because they thought it was too hard. These are users who are not uncomfortable with storing all of their passwords and financial data in a corporate cloud. Over time, once they begin to understand the benefits of better anonymity, they can switch to using sovereign keys.
