Some people will do anything to hold onto their false beliefs even in the face of basic common sense.
Pakistanis should be thanking IMF. If it wasn't for IMF most of your services would be stopped, no money for police salaries, army salaries, teachers, administrators, civil servants - it would be instant chaos.
OP talks about how he never agreed the loan - the fact that you are able to visit your country, the fact that it survives as a sovereign entity is your reward. That's what you have bought with the loan - so unless you take zero benefit from that, then you are party to the loan.
The basic truth is that Pakistan, like most Asian countries is a loss making entity. You earn less than you spend - so unless you increase your earnings or decrease your spending there is no point in blaming the ones giving you a financial lifeline in the meantime.
And you can talk about theft - but even if 10% is stolen, 90% is used for real costs. How else can you have cheap petrol, electricity and millions of people on govt payroll?
