As cruel as this may sound, why not stop giving him some of the luxuries? If you give him the luxuries then he has no need to obtain them on his own because they're provided for him. But if you give him some nudges by cutting some luxuries, then he'll get the idea that he has to get them himself. Don't drop him right away as that'd be hard for anyone to get up from so only cut off some luxuries, starting with the least harmful ones to be cut off.

In addition, you could get him a therapist if needed but don't try to make it seem that you won't stop loving him and such.

I don't see any other alternative because no matter how much you talk to him, at the end of the day, you're still giving him the luxuries. Even if you do get through to him, he knows that he can simply take the easy route. But if you start cutting off some of the luxuries, then the easy route isn't looking so easy and gradually he'll see that living off of you won't be enough.

You could also try to help him find ways to obtain the luxuries without you providing them for him just so he knows a) you're there for him (emotionally), b) you're there slightly for him (financially) and c) you know that he's finding and engaging in appropriate means to obtain the luxuries.
