If Michael was going to be completely honest, he wasn't planning on creating a toll booth for the Golden Road so early in its construction. Of course, he planned to make it a business later on down the line when it was more established within the Royal Continent, but he thought that it would be much further later in the future.
However, creating this [Gate of Rebirth] would necessitate him having to create a membership that would allow people safe entry into the Golden Road.
For example, at the start of every town, there would be a toll booth to enter the Golden Road. Once they paid a certain amount, they would then receive one of his Shadow Clones to accompany them throughout the journey, keeping them safe from the Unity Flames of the [Gate of Rebirth].
This was actually a tremendous idea if not for Michael being a little bit hesitant in making people pay for passage into the Golden Road.
