Yes, as it is now. But you have to replace it with something better. You're not anti-welfare but to develop public organisations not beholden to market conditions and not beholden to the capitalist state either. Another way to put it is that we need to counter the left-liberal notion of the welfare state by offering our own, and decoupling the former from the capitalist state while at the same time not speedrunning those offerings through the private sector. A public sector that is not beholden to capital - either at the capitalist state level or the private sector level.

How is the big question though. Because the above will also need to then inevitably solve both food production and currency production (ie you need tokens to represent labour).

The contradiction to solve for western communists is this: the welfare state is subsidised through the unequal exchange of imperialism (eg the New Deal effectively heightened the brutality of imperialism - Jakarta Method as a more famous example), it also materially provides the structures to ideologically increase the divided between western workers and global south workers, effectively dissolving that international solidarity.

However, history also suggests that western workers on a whole turn towards more overt* fascism when precarity is turned up ie to steal more violently the remaining piece of the surplus value pie. You therefore need an effective vanguard to combat this but that vanguard also needs to offer something in the short term material benefit; you cannot rely on the hope of "empathy".

In the US red power movements and new afrikan movements have ideas (I will have to research this more deeply, ie beyond what the likes of what Black Panther have done) on how to do this but they are effectively quite disorganised as whole after decades (if not centuries depending on how you want to define the movements) of brutal state suppression - the current prison system and police system is largely built on the foundations of kneecapping these most revolutionary of US folks.

So short answer is Losurdo is right but not from a left-liberal perspective. You can't say "no welfare state" and then not offer something that is (1) significantly better (2) feasible. It requires careful creative and thoughtful collaboration to solve this.

(This ain't pie-in-the sky by the way. I just don't personally have a solution for the west. If you look at the global south, things like the Kumbasahree network in India (a capitalist state) is a partial example of this but it required a more local state capture to embolden it. Western communists on the whole should collaborate more with global south communists - you're not going to build actual international solidarity without it - but people get upset when questioned why the likes of PSL effectively refuse to touch these pertinent questions. They have no answer to the question of labour aristocracy)

*there has to be a better way for me to articulate this (but I don't have the mental fortitude or skill at present to convey this at present. I'm too fucking tired). Because fascism isn't a WWII-esque phenomenon. It has been there since the birth of capitalism: https://redsails.org/really-existing-fascism/
