While I agree with most of your post, this doesn't seem to be entirely correct. At least it needs a clarification.

Here's a chart of BTC (blue) vs. BCH (red) vs. BSV (yellow) in terms of transaction count:



One can see that while BCH most of the time (exception: during much of 2021) indeed saw much less transactions than Bitcoin, BSV had phases (for several weeks each) where it had up to 100 times Bitcoin's transaction count.

This however is the product of the big block policy: in the BSV community, some apps were developed which could be considered outright spam, like one registering climate data on-chain. It's also highly likely that at least some of these apps were developed by the BSV team or paid by them to demonstrate "usage".

One can say that if BSV saw "real" usage it would have probably massive problems with node decentralization, as the requirements for full nodes would be astronomical.

In terms of "real usage" you probably are correct that there are few "genuine" transactions. However, I am still surprised how well in general BCH is holding its price, it's almost always between 200 and 500 USD per coin. Its price against BTC however is falling almost constantly.
