This is bad at least a dozen reasons. The most fundamental one is an unwillingness to accept a material reality. The second one is an unfamiliarity with the best arguments against material reality.

Light projects from a light source -> Some of that light bounces off of my fern -> Some of the reflected light reaches my optical nerves -> This triggers a bio-electrical signal in my nervous system -> The patterns of bio-electrical signals are recognized by my brain as my fern.

There is a physical reality of photons and carbon atoms and the medium of space/time in which all of this occurs. Some people get so caught up in what's happening in the nervous system that they discount the very large amount of empirical data we have that demonstrates the existence of a physical reality. Even if we are in a simulation, the simulation seems to be operating this layer we call physical reality.

Circling back to add more.

Some people get caught up in wave vs particles as well, and think that this someone disproves a material reality. You should always ask these people what is the medium that the wave propagates through. The ocean wave propagates through water. The sound wave propagates through atmosphere.
