Doesn't really matter if the price was inflated or not. Anyone that was eyeing the 3070 class wasn't cross shopping with a 6800 because that was a higher tier of gpu class along with a higher price even at launch and not to mention it was an unicorn that was more unobtainable than a 3080 because of how limited in stock it was. And during the crypto boom, upgrading to a higher class wasn't $80 more, it was more like several hundred dollars more.
These days it's different because everything is in stock and RDNA 2 has had massive discounts below their MSRP. So the situation these days is a lot different but those days, I think the 3070 was a valid choice given the alternatives.
