Questions: If one gets PI space from ARIN for their network, then moves the servers to a rack at a data center (still using the space efficiently), will most colocation providers announce this space for them, or would most providers require them to take allocated space from them? Is it a

Routing slots aren't the only resource you're consuming. In general, many of the prefixes coming out of a given AS have common attributes, e.g. path, MEDs, etc. Those attributes are stored only once (at least in the BGP implementation I know) even if they're used by hundreds of
