I must disagree, but before I do, I want to be clear that I have nothing to say about you liking to have real estate and having it work for you, that's your choice, and it's fine.
But, you (maybe unknowingly) are putting up a straw man argument against a portfolio. A couple things you just have wrong:
1) A portfolio must be measured by Total Return. It's basic arithmetic, it's the only thing that matters. If it didn't, not a single person with a single functional brain cell would purchase BRK, it provides zero "income", and has an almost zero chance of ever providing "income". Yet many people have done very well with it. It's not an illusion, it is real money. Total Return. Period.
A balanced portfolio 70/30, returned ~ 10.99% in the past 12 months. More than double the number you are using. Using the 10.99 number, your 40% portfolio should have provided 78.8% of your monthly spending. Sure, that number will vary more than the divs alone, but it also will outpace divs alone in the long run.
2) A stock/bond portfolio does not require active pursuit. A "couch potato" portfolio has been shown to out-perform most attempts at active management.
