Fair point. And thats the only reason you'd not want teams like Pool to win it but i think our fortunes and reputation as a club depends on if we can win a CL more than other clubs winning it. PSG, City, Chelsea(to a lesser degree) have no European heritage, doesnt stop top players from joining them.
The best is obviously to win it, but being dwarfed even more so year after year does reduce our overall prestige and improve the one's that one upped. It's a constant change of dynamics
It doesn't stop them from joining those teams but they're not the last in the foodchain given their history, Barca, Real and Bayern will be more attractive as long as they're up there at the top. For Real Madrid and Barca even when they're not
But that's besides the point, a fan should care about how their club compare historically with the others because that's what's count. Doesn't mean that since we maybe won't win one soon that it'd be preferable to be dwarfed even more hard. In 50 years 2 CLs is going to be chump change.
