I'd rather we not get rid of a valid strategy in the game. Is it wrong for some players to be more prepared with what they're gonna buy, get it quickly, and run out the gate right away?
If your team is slow out the gates, then sit back and wait for 5. The dumbest thing you can do is run into the brush alone assuming your team is right behind you without checking.
And at that, giving up that first blood if somebody does check into a full brush isn't really that detrimental. Pretty easy to come back from that (remember, they really only get a slight XP bump from it because they can't spend that first blood gold right away). And sure, they may push into your tower for the first wave, but it'll reset quickly enough because teams tend to just fast-push waves, rather than making any attempt to freeze the lane. Kinda difficult with 5 people there.
