You can't just say "whether or not I replaced the Bitcoin is irrelevant" - that is *specifically* the topic we're talking about...Namely, IF spend and replace would have kept your stack unchanged.
And the answer is very clearly "yes, it would have been unchanged" as you can see in my directly above illustration.
The only way that would not hold is if you were, back then, planning on buying Bitcoin INSTEAD of pizza (as opposed to **in addition to** - which is the definition of spend and replace) with those same dollars that went to the pizza (the timing of the dollars is highly relevant, of couse).
