The government will make Bitcoin the same way illegal as US dollars.

Then they can't easily control Bitcoin.

Then they will increase prison sentences for owning Bitcoins and Bitcoin apps.

Then they will not be able to control that.

Then they will monitor the internet for bitcoin transfers.

Then they will outlaw any encryption.

Then they will send out undercover police who try to pay with Bitcoin.

etc.

No government well let anyone take away their privilege to print money.
