I’m a member of the National Trust. For an annual subscription I get free parking and free entrance to all their properties and can visit any of them as often as I wish. If I resign from the National Trust, I will have to pay parking and entrance fees every time I visit a National Trust property. The National Trust are not penalising me by imposing those charges, only applying the charges that apply to all non-members, which I chose to become by resigning.
It’s a bit like the EU.

Why are you considering resigning?
Not from the National Trust, and it was a forced resignation from the EU.
I thought leaving the EU was a stupid idea too.
