That's literally impossible under capitalism. Blahaj is a commodity like any other, you can't attribute ownership to a certain group of people based on their qualities (welcome back racial segregation), and trans people aren't automatically more virtuous because of their struggles, so a trans small business owner selling Blahaj plushies for a living isn't immune from going full Hitler and abusing their workers, PR to get as much profit as possible.
One of the worst job application decisions you can make is working for a small business owner, given their legal exemptions in discriminatory laws, them always being on the edge of going bust causing them to take psychotic measures to increase profits, and very little infrastructure in place at the job location due to their lack of money causing safety/medical issues.
I saw that before writing the comment, and it doesn't really change anything. If you want a blahaj of your own and got the sewing skills (from the looks of it you do need to be quite skilled), then sure but if you want to commercialize it and start sewing for others, you're now a small business and my comment above elaborates on what usually happens with small businesses.
