The problem with your idea is that your token isn't pegged to anything. You can't create value that way. Burning ETH will only make ETH's value go up, not your token's. In other words, if you burn 1 ETH, you'll only make ETH slightly more scarce.
when you spend ETH for the token you have intention to get something in exchange of ETH with real value, and this "something" really does have a value for you cause you spent real money for that
So the token doesnt need to be pegged to anything the same way like ETH doesnt need to be pegged to anything.
Look at this token not as at regular token with collateral - but as at a product you buy
Look, you completely missed the mark on pegged tokens. Your claim that collateral multiplies the money supply? That's wrong.
Again, burning something valuable for your token doesn't magically make it valuable. Seems you're forgetting the other half of the equation. Imagine this: a wacky billionaire buys all the sand in the Sahara for some eccentric reason. Does that magically inflate the value of every grain of sand on Earth? Of course not! The same thing applies to your token.
