I haven't followed in detail your debate, but I"ll just say that I'm very happy that this conversation is being had in ~math

I wasn’t sure what I meant when I said it either

I'm not following. My engineering mind interprets: shortening an infinite series to the first elements for which a value converges well enough for practical purposes. But I'm sure that's not what you mean

I’m aware of some people who think infinite sets are an example of something that needs to be pruned, which would reduce the domain of sets to only having a defined number of elements.
