You believe the airline is less likely to honor an excess valuation that you paid a fee for than an insurance company that you likewise paid a fee (premium) for? Delta charges $50, for example, if I declare a value between $4,000-$5,000. Would Delta take my money and then when they lose my bag say "sorry--we're not honoring that"?
They would. They do it every day. There's a long list of exclusions, among them electronics and photographic equipment, and "recreational/sports items that aren't in hard-sided case," and items for which you "don't have proof of loss or receipts."

Other carriers are similar. They treat baggage liability as a cost to be minimized to the extent feasible, and not as an area where they're trying to provide good customer service. Way the world works.
US-based homeowner's insurance policies typically cover your stuff when you travel. Claims service varies but the better insurance companies generally pay their claims.
