Yes, it would dangerous and detrimental to view to stand in the Top Balcony throughout a match. Kids would probably need to stand on seats to see the near touch line and assisted or that would be accidents waiting to happen.
It used to be such a simple decision at Goodison. You stood up downstairs (if you were skint) and you satdown upstairs (if you were flush). When the Street end was first seated, people mainly sat down. I think most people probably thought that: "I've paid for a seat, and I'm going to use it" and can remember being urged to sitdown by those behind me, after standing for an incident/corner etc. At some point, standing became the norm, but I still see some sitting towards the front. The only problem with standing, is the Street end was reprofiled for seats, so when people stand, the view worsens as the designed c-value falls significantly. For standing areas, you actually need higher c-values for clear views, because there is a far greater range in standing-heights than seated-heights.... meaning short-arses standing behind giants see little or nothing (which is what happened for me at West Ham haha). At least in the days of terraces, you were free to move around to find that decent speck, perfecting it over years of experimentation. Which was even more important when the Lower Gwladys St held almost 15k as opposed to the meagre 6k or less of nowadays. Of course standing at the side is different to standing behind a goal. Obviously the goals are the main focal points and at least at the sides, you are set a good distance away from them. My dad's old favourite vantage point in the days of terracing was actually the Lower Bullens Area. Much maligned nowadays of course, but tt was a slightly raised shelf of terracing above the paddock which, if you avoided an obstruction gave a good vantage point under cover.
When a lot of new stands were designed at the beginning of the all-seated era, they didn't really take standing into account.... and while they mostly offered great views when everyone was seated, this diminished massively as more fans started to habitually stand, trying to reclaim terrace culture, or counter the stagnant atmosphere etc. If you've ever stood on the Kop at Anfield towards the sides, you'll know that in parts it's no better than the old one for view. You see this at several away grounds where away fans mostly insist on standing. Hopefully a high standing c-value will have been designed into the safe-standing areas at BMD, and not just for when seated. It's a shame that they didn't go for a safe-standing paddock/enclosure on the sides too.
