I wouldn't be wanting us to bid £100m (or whatever figure Spurs find acceptable) this summer, but if the opportunity is there to get Kane on a free transfer next summer, I'd absolutely want us to be in the mix. Getting Kane in, or another player with equivalent goalscoring record, is the best way to close the gap to City in the shortest period of time.
If he is the difference between us potentially winning a league title or not, you worry about the longer term issues of player happiness later. City have two in Haaland and Alvarez. They won't both be happy with that forever, but in the meantime they're hoovering up. You'd like to think Hojlund will be a hit but there's no guarantee of that happening either, it minimises risk. It might well be that Kane falls off a cliff when he's 33 or 34 as well, in which case you have Hojlund coming into his peak years at 23 or 24 years of age. I think it would make a lot of sense.
