What is the guarantee that myTREZOR.com will always be around for me to be abel to spend/receive bitcoins using the Trezor?
In 30 years, will that website still be around?

If push comes to shove, you can host your own: https://github.com/trezor/webwallet
Might be hard to replicate the backend, though (but I think it's opensource).
Another solution would be to use other wallets. Electrum and Armory will likely have trezor support soon.
Also, there's a library to access the trezor: https://github.com/trezor/python-trezor and there are also other ways to use your seed and get to your money. There are standards for the format and such (bi0032, bip0039, bip0044).
You're in no way dependant on myTrezor.com and I think it's not unlikely it will be gone in 2044, your trezor still alive and kicking
