Taproot didn’t do anything to help shitcoins, I don’t know how that became a popular trope about all of this. In fact, despite it not being used, taproot is how you could do that stupid garbage without it bloating the blockchain at all.
The only bit thing with soft forks that gave a lower cost to inscriptions that were fully printed onto the chain was the Segwit *discount,* which wasn’t even really about Segwit itself, but was simply what was done to get a compromise blocksize increase during the shitstorm of a war that had gone on for 4 full years.
