Well, here's my problem with that. This is one of those "take it for what it's worth" moments. What you hear on a record usually has a bass guitar, a rhythm guitar, a lead guitar, drummer, percussionist, maybe a sax or trumpet player, and some dude on harmonica plus a couple chicks banging on tambourines. You have an acoustic guitar. Good luck trying to replicate that.
If you try to replicate the sound of a whole band with an acoustic guitar, you won't.
Listen to a really good solo bar guitarist. What you will hear him play will be pieces and parts of the drum beat, the percussionist's fills, the rhythm guitar's strums, and the lead guitarist's riffs all blended together. That's as close as you're ever going to get to "replicating" a piece without a band.
Whether you want to or not, you're going to either have to put together a tribute band with common interests in perfectly replicating studio recordings, or you're going to have to wrap your head around the concept of arranging a piece to solo work.
Are strum patterns important? Oh heck yeah! Is it the most important thing? Not even close. Keeping time is the most important thing, followed closely by staying in key. By the time you figure those two things out for any given song, you're arranging.
