In another question a user asked about how to come to grasp with the idea of fractals bounded by infinite area containing only finite space. I'm familiar with this property but I am befuddled by one of the comments given to the post. The specific comment is:
"There's another fundamental problem here: if you give the Koch snowflake finite thickness, then it cannot exist. Each arm of the snowflake has infinitely many sub-arms, ad infimum. This implies that if you have a non-zero thickness $T$, then each arm has a minimal width at it's base of 2$T$ which would imply the snowflake has finitely many arms"
This does not makes sense to me, what is to stop each of the Koch's curves infinite arms from having finite thickness. How does one describe the surface obtained by continuously translating the koch's curve $1$ unit through the $z$-axis? or the surface described by the equation of a Koch's curve with free but bounded $z$.
