Root mass and pot size

ok I am new to this and I've gotten a diffrent idea and alot of people try to get their plants to the biggest pot size fast but I was wondering because I want to have tall mom and dad plants would having them in the smallest pot size be better and move up to a bigger size so that the roots don't just go to the bottom fast and become rootbound

the plant needs a large root structure.. you can force it to become rootbound, but it will stunt the growth of the plant.. big containers are always better..

yea but once I get my closet up and running I want to have plants as close to 7 feet tall as I can and that's kinda why I was thinking about making them get root bound on perpous so that I can get the most root system in an area because roots do go down and having a big contanor would meen the roots will go to the bottom and waits alot of the top and mid space am I correct?
