Most payments in the future will be Layer 2's & 3's  etc & most bitcoin isn't moving at all these days.  We had huge spikes in transaction fees in 2017 and there were no ordinals back then. I think ordinals are stupid but I'm with the likes of Jameson, Odell, Adam Back & others who say don't worry about them. Besides, Luke Dashjr is helping to create a mining pool that rejects ordinals/inscriptions so there will be a way to avoid them.
