Reply to Making beats: starting from scratch vs using pre-made loops

This is a question I've had for a while now, and I'm not sure if its actually a good question, or an incredibly obvious stupid question. Before I even thought about getting into DJing, step 1 was to fool around with Garage Band that came with my mac. Well that quickly turned into around 30 or so tracks but instantly got me believeing about loops. When using Garage Band one is instantly set up with a vast library of various loops. So naturally I took advantage of this, almost exclusively when it comes to beats. For me beats are pretty complex; its easy to write a melody or a bass line, but getting good drum grooves can be tricky. Almost immediately it got me believeing: what is the general view on using pre-made drum loops or sounds in your tracks? Is this frowned upon as being essentially "cheating"? Would one ever be taken seriously layering pre-made drum loops to make a groove as opposed to creating every individual sound for yourself, or worse selling your music only to find out these loops are subject to copyright laws?

My natural instinct is to believe that yes, this would be frowned upon because to me this is by far the hardest part of making a track (hence why I believe this might be a really stupid question). And yet I've seen no shortage of add-on packs and loops for Logic and Abelton (but why I believe this might actually be a legit question after all). I'm now on the verge of getting back into the producing side, this time on Ableton (god help me) and I want to do this right. Layering pre-made drum sounds would save me a ton of time and hassle if it's legit, however getting good at creating them from scratch would obviously be a great skill to have. Any thoughts?
