i guess my question is why is it not a default thing for regular user pcs. why do i have to buy a new cpu, why can't i buy 4 amd cpus instead of buying that i7

  Because it'd be more expensive and complicated, and thus nobody would buy that stuff. Was slightly different at some points in the past, where more enthusiasts had them, but back then CPU speed was something that really mattered for consumers. + market segmentation: if you really need multiple CPUs, you likely are willing to pay for it.

  you can't strap N cpus together and get the same performance as a single fast CPU unless you have problems that map well to that. It's cost effective for intel or AMD to throw multiple cores on a die, but less effective to put multiple sockets on a motherboard as the motherboard now needs a bunch of expensive traces between all the sockets to handle the communication which is required to parallelize algorithms. It's just not cost-effective. And you can buy dual socket machines- they start around $2K which is about 4X the cost that a consumer wants to pay.
