Is The Personal Brand Limiting?

First of all - thank you every single one who commented in my previous post, I have fully gone over and grew out of that stupid fear of "ideas being stolen" plus I have realized, it isn't the idea which makes business great, but the execution behind it, if you fear someone doing better than you, you're not executing enough - and overall, abundance mindset helped me a lot, Pepsi and Cola for example both have lots of fans, even though they're almost the same thing, just... abstract from the #1 leader and create your own category, blue ocean strategy and etc. etc... so

I was just very curious, so I have lots of friends in Russia with insane media fame, one of them is a TikTok guy with a half a million followers, and his audience is Russian, then another guy, who has 8k followers in Telegram and 200k in TikTok probably, and he sells his coaching and courses; so... will it limit me to one business?

I feel like, if I create a business and brand it with my face and voice & body, people are gonna associate me with that business, so that when I want to go different route, my reputation will be "oh it's X guy" and if I start to gain audience in US, then Russian audience is still gonna come over there to kinda... make fun jokes in comments, and just let me stay theirs?

Should I even start a personal brand?

Or will personal brand associated with me grow, and I can change the business anyway, and association with me as one thing to another?

Thank you for your answers in advance, hopefully I wasn't that confusing
