Segwit increased the block size limit, not Taproot.

If it makes people feel better to not relay graffiti, then all the power to them. However, I do think it's largely performative, not going to have a tangible effect on the amount of graffiti that ends up in the system (just like it hasn't for the past 2 years), and thus is kind of a false promise and unproductive use of mental resources.
