Explicit consent will be everywhere, like you won't be admitted to a grocery store without it. Take any modern TV -- there's a privacy policy you have to accept the first time you turn it on. Or California Prop 65 notice on every product.
So no, requiring explicit consent won't fix anything.
The government needs regulation to allow access without granting consent in certain cases. Not quite as far as declaring something a utility, but better than almost completely unregulated.
