The high fees of gwei in Ethereum transactions are due to the supply and demand dynamics of the network. When the network is congested, users need to pay higher fees to prioritize their transactions. The popularity of DeFi and NFTs has increased demand for Ethereum transactions, leading to higher fees.
you can always alternatives for the purchase of what you are trying to do, if for example you are building an app on top ethereum, you can go for other chains with lower gas fees, I had the same issues with etherem, i have to migrate to stellar because they have lower gas fee.
maybe if its for testing purpose that's still make sense changing over to other chain if one is building an app, but it might be better to use the test blockchain instead.
the thing is that, you still have no choice but to deploy in ethereum blockchain if you wanna make your app meaningful, despite the high gas fee, it's still can't be denied that ethereum blockchain, in term of traffic far better than the rest of the alternative.
therefore it still make sense to deploy an app in ethereum instead, even layer 2 aren't having the same ecosystem like ethereum and recently many coins that has gained success are all in ethereum blockchain, so I doubt you could just move on to another alternative blockchain that easily.
