Regulated capitalism is still capitalism. There’s no such thing as “pure” or “impure” capitalism, the social relationships to capital are the same. Lassiez-faire capitalism is just a flavour of it.

It’s like ice-cream: you may prefer chocolate ice-cream over vanilla ice-cream, but they are both flavours of ice-cream and you wouldn’t say “yea, that’s not pure ice-cream”. Some people may even dislike ice-cream altogether and prefer cheesecake.
