yes, just read the news that driving licenses have to be linked with aadhar. Phone numbers have to be too. Pretty soon it would be impossible to do anything without aadhar = end of privacy
With the heavy push for linking it almost everywhere, the government could also use it against individual citizens (dissidents) to cause "civil death" - can't drive, can't use bank accounts, can't study in schools/colleges, can't have a cell phone number, can't have a salaried job (where tax is deducted at source and PAN is expected to be linked), can't get pension...can't even conduct a funeral for a relative (this is the latest move - death certificates require Aadhaar of the dead or that of a close relative).
It's truly "one number to rule them all"!!! In the hands of an oppressive government, dissent can be easily stifled and quelled!
