You can do crypto as a side-hobby and safely put it into production. Of course, you can also do it wrong, but it is with little work possible to do it correctly.
Normally I wouldn't speak against what you said because the critique is only very minor, but I heard this too often. Your warning is too strong. People should try their own crypto and with little care it is not unsafer. Maybe giving a list of do's for that would be a good start.
