Agreed. Lindros was an absolute beast at 18, he was basically full grown and stronger than 90% of the guys in the league. The fact that he made Team Canada over guys like Sakic, Linden and Turgeon who were all 3-4 years older than him (Sakic finished 6th in scoring that year) speaks volumes of the unique skillset he brought to the team as an 18 yr old (though Mike Keenan selected the team, he looks for specific players that fit his prototype).
The equivalent for Bedard would be playing for team Canada in a best on best tournament this summer and making the team over Marner, RNH and Point. IF there were such a tournament, it would be hard to imagine him doing that at 18.
