Yeah, I'm not saying do nothing, but the tactics by Dem politicians have to be more subtle than something like court packing, which is drastic and easily understandable compared to something like violating senate norms. And from a historical standpoint, even though FDR won reelection by a overwhelming majority, his court packing scheme was ultimately unpopular with both Congress and with the general populace.
I think it's okay to talk about it, though, as long as we understand and communicate that it's not realistic at this time, because one day it might be (like with Abolish ICE, even though it's more a part of comprehensive immigration reform). It's more about shifting the overton window. But at the very least, the faster we can get people to treat the Supreme Court as partisan (because it already is), the easier it is to use partisan tactics to pressure it (and we can directly protest the justices already!).
