Hrqls: there are also people with busy lives who don't have hundreds or thousands of games going on

Sure but they don't therefore affect hundreds of tournaments and hundreds of other players.

I would further suggest that the number of busy lives who almost always play at the very last minute is minimal. As I pointed out to Roberto, the time controls are not as labelled. The 5-day time control is for 7, 8 or 9 days, not for 5. A game-hoarding slowcoach will often take the full 9 days when it occurs whereas a busy lifer will not.

Hercs: the players do (or should) know what they signed up for

Why "should" they? Did you nod knowingly above, when I said that a 5-day control is for 7 to 9 days? Maybe you did but do you think that it's common knowledge?

Hercs: for prize tournaments: the creator has chose the time limit for a specific reason

Lol. Do you really think that tournaments that can take decades have been given a thoughtful time control? I suspect that most tournament creators do it naively.

Besides, even when they are carefully chosen, the tournament can still proceed very slowly. I used to create tournaments with limited time controls called "Some like it fast". The idea was that they could be over within weeks and thus be suitable for fast players and Pawns. But a slow player can make those take months instead of weeks, perverting the intent, spoiling the enjoyment and degrading the membership of any Pawn who falls foul of them.

The reason that I reject "but they're playing within the rules" as a poor excuse is that it misses the point, which is that the rules are not fit for the purpose.
