I agree with you, but the entire game includes to me also DM restrictions and limitations. I never even played in a game where Volos races were allowed. And usually in my games a build needs to be explained by roleplay limitations and causes too like backstory, world setting etc. As I wrote, roleplay and optimization can get fusioned. With those limitations, you still can optimize your build, the optimal values are just different.Optimized for me means Optimized within the confines of the entire game, not just a class. I.e. you play Bugbear Polearm Master Sentinel Opportunity Attack Fighter because it is broken because there is a 0% chance this happens naturally without browsing Reddit.
A GM with optimizers in the group who allows everything and needs no roleplay will have a party full of broken builds like the one you suggested, but that is not the problem with people who like to optimize, its a problem with the game itself. And usually everyone will realize pretty quickly that this is not very fun and optimizer players without problematic personalities will agree and accept a stricter ruleset where they optimize on new grounds.
