I think it's a small price to pay to have the freedom as a country to talk to anyone in Europe cheaply. The effects won't be felt right away, but just as cheaper flights across Europe have made Europeans much more interconnected, so will cheap roaming fees (even though for the sub-30 generation, WhatsApp calls and such are already the norm).
But the regulation only applies to roaming so it doesn't really affect calls made from your home country to another EU country, which can still be much more than a typical local call.
