For a significant number of troons, especially MTF, they troon out because they do not want to have agency. To be a successful man means to be highly agentic. 99/100 MTFs just want to sit around and smoke pot all day. Being a pet, or a slave, fulfills their dream of not having to make any decisions or do anything of their own volition.
How many MTFs have you seen who fantasize about being a slave who's actually forced to work and do chores? No, they just want to laze around, smoke pot, and get fucked.
This is also why they want to be women. They perceive that women can coast by on a lot less work in life, that they can sell hole on OnlyFans or be some rich guy's sugar baby. They want to be rewarded merely for existing, the way they believe women are.
Troons are natural serfs/slaves, they see their own freedom as a curse, and we should force them into serfdom onto troon-exclusive sharecropper farms. They can exchange their crops for their hormone shots. They get to have their greasy polycule, but they also have to produce something of value.
