Look at almost any padel club's booking terms and you'll find a no-show or late-cancellation fee, often the full price of the court, sometimes more. This isn't one club being strict. It's close to universal across the industry, which tells you the underlying problem is real and expensive enough that venues had to build a financial deterrent around it.
A no-show doesn't just cost the person who didn't show up. An empty court during a booked slot is lost revenue the venue can't recover, since that hour is gone the moment it passes. Multiply that across a season and no-shows become a real line item, which is exactly why booking platforms like CourtReserve and MATCHi build cancellation policies and fees directly into their product.
What rarely gets counted is the cost to the other player. You didn't just lose the money a club might charge you. You lost the evening you'd planned around a game, possibly the only slot you had free that week, and the motivation hit of showing up somewhere for nothing. Venues have a financial mechanism to make themselves whole. Players usually don't have anything, and just absorb it.
The venue side of this problem is basically solved: charge for no-shows, and they mostly stop. The player side hasn't caught up, since informal games rarely have a real deterrent built in. Rally treats reliability as part of your profile, not just your rating, so players who consistently show up get matched with other players who consistently show up, and the no-show problem starts shrinking from the player's side too, not just the venue's.
