I think most people today can run a node and without the limit it gets cheaper over time. 
And I would assume they just can´t afford a node, because they don´t have Bitcoin. 

But tbh I want a BTC where I can easily run a node for myself. And this would be in danger if we would increase the block size. 
So for me it is no question if "any of the existing L2 techs or block size increasing". 
It is just a question of "increasing the block size or not". For me it is not an option at all.
