Counterpoint: The overwhelming majority of curses are either crippling or a complete nonissue. Something like mummy rot will quickly kill a character, and curses that impose penalties on stats or rolls either affect something they use, making the character almost useless, or doesn't, so doesn't matter. If you don't want the party remove cursing a specific curse, just make it more powerful than them.
Counterspelling is bad for a similar reason curses are bad, not remove curse - the overwhelming majority of counterspelling mechanics make it either too easy to too hard. Too hard and it's just not worth trying, and too easy makes combat a matter of who has more casters.
