Once you have one the game (in this case FIRE'd), it seldom makes sense to continue playing - why risk what you have?
I'm in a similar position with enough income from real estate and equities to cover our living expenses and that income stream will grow as mortgages are eventually paid off (and, again, when my daughters are eventually off the payroll). I don't need bonds for income but I have some high quality bonds anyway for two reasons:
1. I have an allocation to cash and put some of it into short dated bonds (<3 years) as the return is higher than available bank deposits/CDs out here and the additional risk is minimal;
2. bonds provide diversification and reduce the risk to my portfolio - their main function is to leave me with less downside rather than generate upside over other asset classes.
