Why you think it is bad idea? I would like to hear you opinion?
Several reasons:
1) You'll be flooding your subs's feeds with your videos. They'll quickly get sick of it and unsub.
2) When a channel is small, often the most traffic comes from people manually landing on your channel page and then watching your latest video. If your latest video is only there for one day, each video is only going to get one day's worth of traffic. That won't be enough views per video for Youtube's algorithm to accurately "decide" if it's a good video. (not a significant amount of "view time" data) so your videos won't tend to do very well in search or in suggested videos. Compare that with weekly videos - Each video gets 7x more of those views.
3) Quality vs quantity. - Better to make 1 amazing video than 7 rushed videos.
4) Burnout - You'll be sick of making videos after about 10 days and it'll start to show.
