You're solution doesn't solve the thing you're trying to solve.
E.g.
There is a "mom & pop" landlord with just 10 properties. But they don't purchase anymore.
Now there are 1000 such landlords.
The landlords all incorporate and create a REIT that owns 10,000 homes.
You have created a "megacorp" through just "mom and pop" landlords.
What is the difference?
The true answer is the abolition of landlords in favour of housing coops and community land trusts.
To prove a point to you I'll ask you a question.
What is the difference between the goal of small landlords vs REITs and "megacorps" represented by row 4 of the graph found here?:
