Do you think it is easier to do well while streaming? Streaming means you have a thousand voices in your ears at once. Is it fun? Yes. But I assure you, I would play much better in solitude. The only "solution" would be not to allow streaming. And really, that would just make it harder to detect.
This isn't about streaming. It's about whether you have a team of players on your couch helping you win one of the season's major Vintage events. And if you're saying you would break rules against outside assistance if you could get away with it because it's "harder to detect" I have no sympathy for that cheater mindset at all.
Edited to add: You know I stream a lot, right? I'm not ignorant of the strategic trade-offs there
