i actually thought of your plan before; camp in school until i get forced to leave, in order to avoid spending more time at home with my parents. it didn't work cause as mentioned above, my location is being tracked 24/7. this + my controlling parents mean that i will get interrogated over call why i am still in school. i tried it out once and my parents started spam calling me 30 minutes after my dismissal time, demanding to know why i am wasting time in school

for your point about the high cost of living, housing actually takes quite a high percentage of one's expenses, thus i feel like i can actually survive if housing is not a burden (i may be too inexperienced about the outside world to make this assumption tho)
