sorry man maybe I expressed myself incorrectly (cause I think we agree on this!).
Basically I agree that payment txs will "push out" data txs, but in a condition where btc is used as MoE and so ppl actually fight for block space and on chain fees are costly. We don't have this codition NOW.
At the moment on chain fees are low, there's no fight for block space, and btc is used as SoV (so little payment txs). In the present condition I think data txs will greatly outperform payment txs. And this is why I don't think NOW it makes sense to say that "data txs will be pushed out by payment txs". Now they will not! Rather the opposite, data txs will push out payment txs! So I agree with you that now is the time to construct dikes to allow payment txs to compete with data txs. In the future we will not need these dike anymore, but now we do.
Did I get it correctly now? Do we actually agree? lol
