The answer is simple: because they are different.
In IPA, the three words buy, pie and spy are represented as [baɪ], [pʰaɪ] and [spaɪ] respectively. In other words, they are three different sounds. This distinction also exists in other plosive/stop triplets, namely d, t, (s)t (dear [diɚ], tear [tʰiɚ], steer [stiɚ]) and g, k/c/q, (s)k/c/q (gill [gɪl], kill [kʰɪl], skill [skɪl]). Putting it differently, p, t, k/c/q are normally pronounced as [pʰ], [tʰ], [kʰ], but when they are preceded by an ‘s’, they are pronounced as [p], [t], [k]. Here are some more examples:
beer [biɚ] dink [dɪŋk] gate [geɪt]

pear [pʰiɚ] tink [tʰɪŋk] Kate [kʰeɪt]

spear [spiɚ] stink [stɪŋk] skate [skeɪt]
