Yes. The game is -not- safe. Compare monster damage capacity with the hps of your standard character. Then take away all healing ability for said character. You'll find character will tend to be very very doomed.
Hps in 4e are much more like a rollercoaster. They go down and up rapidly, and when they go down they go down FAST. Remove the ability to go up, and that character is definately in -great- danger.
Exactly. Back in the 2e days, for example, you had your supply of hit points and that was it. If you got really low then you could use some healing spells or potions to boost you back up, or you could lay in bed for like a month. Either way, you had essentially one pool.
Now, we have a different system. You have your pool of hit points, which in the case of my level 2 Fighter is 42. He has 12 surges, each with a surge value of 13 (gotta love Dragonborn at low levels

Either your players don't have a proper appreciation for what surges represent, or you don't. They're effectively part of your total hit points, you just don't have access to them all at once. Taking them all away means you have removed any ability to heal from damage, as well as having removed 156 of my effective hit point total. This is a huge effect that I think you are not fully appreciating, and isn't a "Safe" situation to be in at all.
