the problem currently has not been the number of TPS but the fact that different groups have incentive to "spam" the blockchain with fluff transactions 1) miners do this to set a minimum floor for transaction fees 2) subversive elements do this to make a point that Bitcoin cannot handle the use cases it was originally intended for really thinking about this it is probably not a problem because the free market should find the true price for an on-chain immutable transaction. coffee transactions will happen off chain and be settled up on-chain (lightning network)
