Here's a chart of BTC (blue) vs. BCH (red) vs. BSV (yellow) in terms of transaction count:
And? It doesn't count off-chain transactions. LN is not traced at all, as well as sidechains, and other second layers.
Also, if BTC would scale off-chain to more extent, for example by enabling decentralized sidechains, then we could have even less on-chain transactions, even if user activity would increase.
Edit: Not to mention, that if you count transactions, then you assume, that "one user is handled by one transaction", which is not true, for many reasons, for example batched withdrawals from exchanges. If you would count UTXOs or signatures, then it would be a bit more reliable (but also wouldn't show you the full picture, because signatures can be aggregated, and many users can hide behind a single signature).
Also, there are coins, where transactions could be combined on the protocol level. Then, they for example have one huge transaction per block. Does it mean, that their usage is lower, because of their transaction count? If cut-through would be introduced, then usage could increase, while the number of on-chain transactions could decrease at the same time!
