The focus in terms of marketing and attracting new people should be like 95% online. utilize X, TikTok and other platforms. I don't like these platforms either but the costs are less, the reach is way way wider and statistically the chances of getting new people are higher.
The only reason i would attend an event if i were you, would be to attract investors and dapp builders, not the masses.
I joined hive back in the steemit days, close to 10 years ago. I literally found it by myself, searching on the internet. 100% of people that are here or were here and i had talked to, found Hive either the same way (searching on the net, watching videos, reading articles) or via word of mouth.
i believe that you have good intentions and the plan seems a bit better than what i have seen so far but i don't think it is the right one for that era
