effectivness of removing triggers for temptations?

what is the effectiveness of removing triggers for temptations (food, entertainment etc ) ? i for example took apart the stationary (to avoid watch youtube videos for example for fun) computer i have but after some time i reassembled it if there wont be one attachment there would be others than even if less obvious attachments - can they be less bad ? monks try to avoid this triggers as well i believe (like asking woman to dress modest when visiting monasteries) so i guess it has its merits i wonder how much of a change to a practice this can make - would love to hear general thoughts on this subject
