Because the GP said "most markets are large enough to accommodate several businesses", but I don't see enough evidence that it's true in your case yet given your lifetime revenue so it's really odd to see you emphatically agree with the GP's assertion and provide your own business as an example.
There's over 200 players in this market, and I've made over 4k so far off a couple hours a day before work (i.e, my main marketing channel is shitposting on twitter) - that's not accommodating several businesses?
